Input
Transmit NRZ Serial Data.
These pins are sampled on the falling edge of
TCLKn when the transmit-side elastic store is disabled. These pins are sampled
on the falling edge of TSYSCLKn when the transmit-side elastic store is enabled.
In IBO mode, data for multiple framers can be used in high-speed multiplexed
scheme. This is described in Section
. The table there presents the
combination of framer data for each of the streams.
TSYSCLKn is used as a reference when IBO is invoked. See
.

Input
Transmit Clock 1 to 16.
A 1.544MHz or a 2.048MHz primary clock. Used to
clock data through the transmit side of the transceiver. TSERn data is sampled
on the falling edge of TCLKn. TCLKn is used to sample TSERn when the elastic
store is not enabled or IBO is not used.

Input
Transmit System Clock 1 to 16.
1.544MHz, 2.048MHz, 4.096MHz, 8.192MHz,
or 16.384MHz clock. Only used when the transmit-side elastic store function is
enabled. Should be tied low in applications that do not use the transmit-side
elastic store. The clock can be 4.096MHz, 8.912MHz, or 16.384MHz when IBO
mode is used.
