Transmit Serial Data Input—Transmit Framer_n:
This input pin along with TxSerClk_n functions as the Transmit Serial input
port for Framer_n.
DS1 Mode:
Any payload data applied to this pin would be inserted into a DS1 frame and
output onto the T1 line via the TxPOS_n and TxNEG_n output pins. If
Framer_n is configured accordingly, the framing alignment bits, the facility data
link bits and the CRC-6 bits can also be inserted to input pin.The signal applied
to this input pin can be latched to the Transmit Payload Data Input Interface on
either the rising edge or the falling edge of TxSerClk_n according to configura-
tions of Framer_n.
E1 Mode:
Any payload data applied to this pin would be inserted into an E1 frame and
output onto the E1 line via the TxPOS_n and TxNEG_n output pins. All data
intended to be transported via Time Slots 1 through 15 and Time slots 17
through 31, within each E1 frame, must be applied to this input pin. If
Framer_n is configured accordingly, data intended for Time Slots 0 and 16 can
also be applied to this input pin.
