Framer Transmit Frame Pulse/Multiframe
Pulse (TFPI/TMFPI[4:1]). TFPI/TMFPI[4:1]
is valid when the S/UNI-QJET is
configured as a DS3, E3, or J2 framer for
non-ATM applications by setting the
FRMRONLY bit in the S/UNI-QJET
Configuration 1 Register to logic 1.

TFPI[4:1] indicates the position of all
overhead bits in each DS3 M-subframe,
the first bit in each G.751 E3 or G.832 E3
frame, or the first framing bit in each J2
frame. TFPI[4:1] is not required to pulse at
every frame boundary in E3 or J2 modes.
TMFPI[4:1] indicates the position of the
first bit in each DS3 M-frame, the first bit in
each E3 frame, or the first framing bit in
each J2 multiframe. TMFPI[4:1] is not
required to pulse at every multiframe
boundary.

Transmit Input Clock (TICLK[4:1]).
TICLK[4:1] provides the transmit direction
timing. TICLK[4:1] is the externally
generated transmission system baud rate
clock. It is internally buffered to produce
the transmit clock output, TCLK[4:1], and
can be enabled to update the
TPOS/TDATO[4:1] and TNEG/TOHM[4:1]
outputs on the TICLK[4:1] rising edge. The
TICLK[4:1] maximum frequency is 52
MHz.
