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 9.8.2. 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
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. When the elastic store is enabled, TCLKn
is used as the internal transmit clock for the framer side or the elastic store
including the transmit framer and LIU. With the elastic store enabled, TCLKn can
be either synchronous or asynchronous to TSYSCLKn which either prevents or
allows for slips. In addition when IBO mode is enabled, TCLKn must be
synchronous to TSYSCLKn which prevents slips in the elastic store.
Note: This clock must be provided for proper device operation. The only
exception is when the TCR3 register is configured to source TCLK internally from
RCLK.
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.
