Signal Name
Used to clock in serial data TXDATI
in serial mode. The sync and data
inputs are sampled on the falling
edge. DS3 Mode Clock = 44.736
MHz E3-G.751/G.832 Mode
Clock = 34.368 MHz
A gapped clock is derived from the
falling edge of TXCKI clock. It is
gapped during Overhead bits that
are not selected to be inserted with
payload on TXDATI. Its polarity is
programmable.
