(1) Typical values are stated for: V_CC = +3.3V, T_A = +25°C.
(2) Peak-to-peak amplitude with sinusoidal modulation per SMPTE RP 184-1996 paragraph 4.1. The test data signal shall be color bars.
(3) Refer to “A1” in Figure 1 of SMPTE RP 184-1996.
(4) Characterized to the limitations of SDI test equipment.
(5) This parameter is specified by characterization over voltage and temperature limits.
(6) Refer to “A2” in Figure 1 of SMPTE RP 184-1996.
(7) Serial Data Output Jitter is total output jitter with 0.2UI_P-P input jitter.
(8) Spec is specified by design.
(9) Measured from first SDI transition until Lock Detect (LD) output goes high (true).
(10) R_L = 100Ω differential.
