Transmit PLCP Overhead Data
(TPOH[4:1]). TPOH[4:1] is valid when the
FRMRONLY bit in the S/UNI-QJET
Configuration 1 registers is logic 0.
TPOH[4:1] contains the PLCP path
overhead octets (Zn, F1, B1, G1, M1, M2,
and C1) which may be inserted in the
transmit PLCP frame. The octet data on
TPOH[4:1] is shifted in order from the
most significant bit (bit 1) to the least
significant bit (bit 8). TPOH[4:1] is
sampled on the rising edge of
TPOHCLK[4:1].

Framer Transmit Data (TDATI[4:1]).
TDATI[4:1] contains the serial data to be
transmitted when the S/UNI-QJET is
configured as a DS3, E3, or J2 framer
device for non-ATM applications by setting
the FRMRONLY bit in the S/UNI-QJET
Configuration 1 Register. TDATI[4:1] is
sampled on the rising edge of TICLK[4:1] if
the TXGAPEN register bit in the
S/UNI-QJET Configuration 2 register is
logic 0. If TXGAPEN is logic 1, then
TDATI[4:1] is sampled on the falling edge
of TGAPCLK[4:1].

Transmit Path Overhead Frame Position
(TPOHFP[4:1]). TPOHFP[4:1] is valid
when the FRMRONLY bit in the
Y10
Y7
S/UNI-QJET Configuration 1 Registers is
logic 0. The TPOHFP[4:1] output locates
the individual PLCP path overhead bits in
the transmit overhead data stream,
TPOH[4:1]. TPOHFP[4:1] is logic 1 while
bit 1 (the most significant bit) of the path
user channel octet (F1) is present in the
TPOH[4:1] stream. TPOHFP[4:1] is
updated on the falling edge of
V5
TPOHCLK[4:1].
