Note 1: “Absolute Maximum Ratings” are those parameter values beyond which the life and operation of the device cannot be guaranteed. The stating herein of
these maximums shall not be construed to imply that the device can or should be operated at or beyond these values. The table of “Electrical Characteristics”
specifies acceptable device operating conditions.
Note 2: Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are referenced to V
zero volts).
Note 3: Typical values are stated for: V
Note 4: This specification is guaranteed by design.
Note 5: R
Note 6: Measured from first SDI transition until Lock Detect (LD) output goes high (true).
Note 7: Peak-to-peak amplitude with sinusoidal modulation per SMPTE RP 184-1996 paragraph 4.1. The test data signal shall be color bars.
Note 8: This parameter is guaranteed by characterization over voltage and temperature limits.
Note 9: Refer to “A1” in Figure 1 of SMPTE RP 184-1996.
Note 10: Refer to “A2” in Figure 1 of SMPTE RP 184-1996.
