Figure 3: DC Termination of Low-Speed LVPECL RXCLK16O, RXCLK16_32O, TXCLK16O Outputs
Figure 4: DC Termination of Low-Speed LVPECL RXCLK16O, RXCLK16_32O, TXCLK16O Outputs
Minimum 5 CLK16 cycles
FIFO Mode Operation
Transparent Mode Operation
Holding RESET “l(fā)ow” for a minimum of 5 CLK16 cycles, then setting “high” enables FIFO operation.
Holding RESET constantly “l(fā)ow” bypasses the FIFO for transparent mode operation.
PLL locked to reference clock.
