Notes:
15. The ratio of rise time to falling time must not vary by greater than 2:1.
16. For a given operating frequency, neither rise or fall specification can be greater than 20% of the clock-cycle period or the data sheet maximum time.
17. All transmit AC timing parameters measured with 1ns typical rise time and fall time.
18. Parallel data output specifications are only valid if all outputs are loaded with similar DC and AC loads.
19. Receiver UI (Unit Interval) is calculated as 1/(f
*20) (when TRGRATEx = 1) or 1/(f
TRG
* 10) (when TRGRATEx = 0). In an operating link this is equivalent to t
B
.
20. The duty cycle specification is a simultaneous condition with the t
REFH
and t
REFL
cycle cannot be as large as 30%–70%.
21. TRGCLKx± has no phase or frequency relationship with the recovered clock(s) and only acts as a centering reference to reduce clock synchronization time.
TRGCLKx± must be within
±
1500 PPM (
±
0.15%) of the transmitter PLL reference (REFCLKx±) frequency. Although transmitting to a HOTLink II receiver channel
necessitates the frequency difference between the transmitter and receiver reference clocks to be within ±1500-PPM, the stability of the crystal needs to be
within the limits specified by the appropriate standard when transmitting to a remote receiver that is compliant to that standard.
