Differential Parallel Transmit Data Input.
The 4-bit or 16-bit data word present on these
pins is multiplexed into a high-speed serial
stream and output on TXDOUT. The data word
size is set by the MODE16 input. The bit order
for transmit multiplexing is selected by the
TXMSBSEL input. The data on TXDIN[15:0] is
clocked into the device by the rising edge of
TXCLK16IN.
Differential High-Speed Transmit Data
Output.
The 4-bit or 16-bit word input on TXDIN[15:0] is
multiplexed into a high-speed serial stream that
is output on the TXDOUT pins. The data word
size is set by the MODE16 input. The bit order
for transmit multiplexing is selected by the
TXMSBSEL input. The TXDOUT outputs are
updated by the rising edge of TXCLKOUT.
Transmit CMU Loss-of-Lock.
The TXLOL output is asserted (low) when the
CMU is not phase-locked to the selected refer-
ence source or if REFCLK is not present. See
LOL in Table 5 on page 10.
