Transmitter AC Electrical Characteristics
Over supply voltage and operating temperature ranges, unless otherwise specified.
Note 12:
Outputs of all transmitters stay in 3-STATE until power reaches 2V. Both clock and data output begins to toggle 10ms after V
CC
reaches 3V and
Power-Down pin is above 1.5V.
Note 13:
This output data pulse position works for both transmitter with 21 TTL inputs except the LVDS output bit mapping difference (see Figure 15). Figure
16 shows the skew between the first data bit and clock output. Also 2-bit cycle delay is guaranteed when the MSB is output from transmitter.
Note 14:
This jitter specification is based on the assumption that PLL has a ref clock with cycle-to-cycle input jitter less than 2ns.
