AC Electrical Characteristics
Over supply voltage and operating temperature ranges, unless otherwise specified.
Note 9:
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 10:
This output data pulse position works for TTL inputs except the LVDS output bit mapping difference (see Figure 8). Figure 9 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 11:
This jitter specification is based on the assumption that PLL has a ref clock with cycle-to-cycle input jitter less than 2ns.
