# The second condition catches the confirmed failure mode on this hardware: # A) Normal LP-low (~342–380 ns) → bridge misses SoT → returns to LP-11
# LP-11 → LP-01/LP-00 preamble (normal ~342 ns) → bridge misses SoT # Signature: lp11_to_hs fires at real LP-low end (~347 ns), hs_amplitude ≈ 15–30 mV.
# → driver returns to LP-11 without entering HS mode # Guard: lp11_to_hs >= LP_LOW_DUR_MIN_NS prevents DC-content false positives
# → burst window is DC LP-11, hs_amplitude ≈ 15–30 mV (vs normal 105–122 mV). # where the ~3 ns noise spike fires the gate but HS IS present.
# In this case lp_low_duration_ns = ~342 ns (above threshold), so the LP-low #
# check alone produces a false negative. # B) Short LP-low (50–200 ns, vs nominal ~342–380 ns) → marginal SoT timing
# → HS burst starts but is weak, hs_amplitude ≈ 40–60 mV (vs normal 100–122 mV).
# Signature: lp_low anomalously short, lp11_to_hs fires at noise spike (~3 ns).
# The lp11_to_hs guard cannot be used here (noise spike looks the same as mode A
# false positives), so LP-low duration itself gates the amplitude check.
# Confirmed example: capture 0120 (lp_low=108 ns, lp11_to_hs=1.7 ns, amp=49 mV).
# #
# Only flag DAT lane (CLK is continuous HS — LP states not expected). # Only flag DAT lane (CLK is continuous HS — LP states not expected).

<h2>Claude Assessments</h2><h3>Capture 0079 [20260417_091529] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 12.2 ns is far below the SN65DSI83&#x27;s required ≥ 50 ns minimum for reliable SoT detection, at only ~24% of the threshold. The LP exit-to-HS transition of just 0.6–1 ns confirms the LP-01/LP-00 preamble states were essentially skipped, giving the bridge no meaningful window to recognize the start-of-transmission. Despite the HS amplitude (116 mV) and LP-11 voltage (1.015 V) being within normal ranges—indicating the PHY is electrically healthy—the critically truncated LP-low plateau means the SN65DSI83 almost certainly missed this SoT entry, resulting in a lost or corrupted video frame and visible flicker.</pre><h3>Capture 0082 [20260417_091657] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 6.8 ns is dramatically below the SN65DSI83&#x27;s 50 ns minimum requirement for SoT detection — it is only ~14% of the needed duration. The LP exit-to-HS transition time of 0 ns further confirms that the LP-01/LP-00 preamble states were essentially absent or too brief to be resolved, meaning the bridge almost certainly missed the start-of-transmission. The slightly elevated HS amplitude of 131 mV (above the normal 105–122 mV range) suggests the transmitter may have entered HS mode abruptly without proper state progression, consistent with a truncated entry sequence that would cause the SN65DSI83 to lose frame sync and produce visible flicker.</pre>

<h2>Claude Assessments</h2><h3>Capture 0026 [20260417_095000] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 33 ns is well below the SN65DSI83&#x27;s required 50 ns minimum for reliable SoT detection, and the LP exit-to-HS transition of only 3 ns (versus the 50 ns spec minimum) confirms that the LP-01/LP-00 preamble states were too brief for the bridge to properly recognize the start-of-transmission. With these two critical timing violations—LP-low plateau at 66% of the required minimum and the LP exit duration at just 6% of spec—the bridge almost certainly missed the SoT, resulting in a lost or corrupted HS burst. The HS amplitude of 116 mV is healthy and the LP-11 voltage is in spec, so this is purely an LP timing issue causing the flicker, not a signal level problem.</pre><h3>Capture 0051 [20260417_100005] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 27 ns is well below the SN65DSI83&#x27;s required ≥ 50 ns minimum for reliable SoT detection, and the LP exit-to-HS transition time of 0.1 ns confirms the LP-01/LP-00 preamble states were essentially absent. Additionally, the HS amplitude of 42 mV is far below the normal 105–122 mV range and sits below the 50 mV threshold, indicating the bridge almost certainly failed to lock onto the HS data burst. These three compounding failures — insufficient LP-low plateau duration, missing LP exit timing, and sub-threshold HS amplitude — make it virtually certain the SN65DSI83 missed this SoT, resulting in a dropped or corrupted frame and visible flicker.</pre><h3>Capture 0052 [20260417_100044] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau measured at 25.7–26 ns is roughly half the SN65DSI83&#x27;s required ≥ 50 ns minimum, meaning the bridge almost certainly failed to detect the Start-of-Transmission. The LP exit-to-HS transition of 0–0.1 ns further confirms that the LP-01/LP-00 states were essentially absent or far too brief for reliable SoT recognition. Although the HS amplitude (128 mV) and LP-11 voltage (1.016 V) are within or near normal bounds, the critically short LP-low preamble is the dominant failure mode and would cause the SN65DSI83 to miss this HS burst, resulting in visible display flicker.</pre><h3>Capture 0053 [20260417_100121] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 46.4 ns is below the SN65DSI83&#x27;s required 50 ns minimum for reliable SoT detection, and the LP exit-to-HS transition of only 2.9–3 ns is drastically shorter than the 50 ns specification minimum, indicating the LP-01/LP-00 preamble states were too brief for the bridge to properly recognize the start-of-transmission. The HS amplitude of 131 mV, while indicating an HS burst did occur, is slightly above the normal 105–122 mV range, suggesting possible impedance or termination anomalies that could compound the timing issue. With both the LP-low plateau and LP exit duration failing spec, the SN65DSI83 almost certainly missed this SoT entry, resulting in a dropped or corrupted video frame and visible flicker.</pre><h3>Capture 0063 [20260417_100527] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau is reported as `None` (absent), and the LP exit → HS transition time is 0 ns—both far below the SN65DSI83&#x27;s required ≥ 50 ns LP-01/LP-00 preamble for reliable SoT detection. Additionally, the HS amplitude is 0 mV (well below the normal 105–122 mV range and below the 50 mV detection threshold), confirming the bridge almost certainly did not recognize valid HS data in this burst. Together, the missing LP-low preamble and absent HS signaling mean the SN65DSI83 would have failed to lock onto the start-of-transmission, producing a visible flicker event on the display.</pre><h3>Capture 0084 [20260417_101343] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 42.9 ns is below the SN65DSI83&#x27;s required 50 ns minimum for reliable SoT detection. Additionally, the LP exit-to-HS transition of only 1 ns (vs. the 50 ns spec minimum) indicates the LP-01/LP-00 preamble states were essentially skipped, making it nearly impossible for the bridge to recognize the start-of-transmission. The HS amplitude of 49 mV is also critically low—well below the normal 105–122 mV range and at the threshold of being classified as absent—which further confirms the bridge likely failed to lock onto the HS data burst. All three anomalies together make this a clear flicker event.</pre><h3>Capture 0087 [20260417_101509] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau of 34.1 ns is well below the SN65DSI83&#x27;s required ≥ 50 ns minimum for reliable SoT detection, falling short by nearly 16 ns (~32%). Additionally, the LP exit → HS transition time of 0 ns confirms the LP-01/LP-00 preamble states are essentially absent or too brief to be properly resolved, which the bridge needs to recognize the start-of-transmission sequence. Despite the HS amplitude (119 mV) and LP-11 voltage (1.016 V) being within normal operating ranges—indicating the PHY is otherwise functional—the truncated LP-low plateau means the SN65DSI83 will almost certainly miss this SoT event, causing a lost video line or frame and resulting in visible display flicker.</pre><h3>Capture 0092 [20260417_101718] — FALSE ALARM</h3><pre style="background:#f5f5f5;padding:12px;border-radius:4px;white-space:pre-wrap;font-size:0.88em">YES
The LP-low plateau is completely absent (reported as `None` / 0 ns), far below the SN65DSI83&#x27;s minimum 50 ns requirement for SoT detection. Additionally, the HS amplitude of only 5 mV is well below the normal 105–122 mV range and even below the 50 mV &quot;absent&quot; threshold, confirming the bridge could not have locked onto a valid HS data burst. Together, the missing LP-01/LP-00 preamble and effectively absent HS signaling mean the SN65DSI83 would have failed to recognize this transmission entirely, producing a dropped frame and visible flicker.</pre>
