Propagation Delay Specifications
1. Delay in 77.78 MHz system clocks from the Tx line input to the LVDS backplane output is seven clocks (see
2. Propagation delay from a change on the PROT SW pin to a protection switch activity:
3. Propagation delay from A1 STS-1 #1 arriving at LVDS input to RX_TOH_FP is 56 SYS_CLKs, and
4. Delay from CS_N going active (CPU write access to reset the chip) to reset being deactivated and CPU inter-

NORM to HI-Z:
— Five rising edges of SYS_CLK from assertion of the PROT_SW_A/C pins to the data changing to HI-Z.
NORM to MUX switch:
— Eight rising edges of SYS_CLK from assertion of the PROT_SW_A/C pins to the data changing from stream

six TOH_CLKs. This will vary by ±14 SYS_CLKs, 12 each way for the FIFO alignment, and ±2 SYS_CLKs due
to the variability in the clock recovery of the CDR macro.
