5. PIN DESCRIPTION
5.1 Transmit Formatter LIU Interface Pins
NAME
TYPE
FUNCTION
TPOS/
TNRZ
O
Transmit Positive Data Output/Transmit NRZ Data Output. If BIN = 0 in the MC1 register, the LIU interface
is in dual-rail (POS/NEG) mode. In this mode, the transmit formatter outputs the serial data stream in
alternate mark inversion (AMI) format. TPOS = 1 signals an external LIU to drive a positive pulse on the
line, while TNEG = 1 tells the LIU to drive a negative pulse on the line. If BIN = 1, the LIU interface is in
binary (NRZ) mode. In this mode, the transmit formatter outputs the serial data stream in binary format on
the TNRZ pin. TNRZ = 1 indicates a 1 in the data stream, while TNRZ = 0 indicates a 0. If TCLKI = 0 in the
MC5 register, data is clocked out of the formatter on the rising edge of TCLK. If TCLKI = 1, data is clocked
out on the falling edge of TCLK. MC5:TPOSH = 1 forces TPOS/TNRZ high. MC5:TPOSI = 1 inverts the
polarity of TPOS/TNRZ. Setting both TPOSH = 1 and TPOSI = 1 forces TPOS/TNRZ low.
TNEG
O
Transmit Negative Data Output. If BIN = 0 in the MC1 register, the LIU interface is in dual-rail (POS/NEG)
mode. In this mode, the transmit formatter outputs the serial data stream in AMI format. TPOS = 1 signals
an external LIU to drive a positive pulse on the line, while TNEG = 1 tells the LIU to drive a negative pulse
on the line. If BIN = 1, the LIU interface is in binary (NRZ) mode. In this mode the transmit formatter outputs
the serial data stream in binary format on the TNRZ pin, and TNEG is driven low. If TCLKI = 0 in the MC5
register, data is clocked out of the formatter on the rising edge of TCLK. If TCLKI = 1, data is clocked out on
the falling edge of TCLK. MC5:TNEGH = 1 forces TNEG high. MC5:TNEGI = 1 inverts the polarity of TNEG.
Setting both TNEGH = 1 and TNEGI = 1 forces TNEG low.
TCLK
O
Transmit Clock Output. TCLK is used to clock data out of the transmit formatter on TPOS/TNEG (dual-rail
LIU interface mode) or TNRZ (binary LIU interface mode). If TCLKI = 0 in the MC5 register, data is clocked
out of the formatter on the rising edge of TCLK. If TCLKI = 1, data is clocked out on the falling edge of
TCLK. TCLK is normally a buffered (and optionally inverted) version of TICLK. When either line loopback or
payload loopback is active, TCLK is a buffered (and optionally inverted) version of RCLK. When a clock is
not present on TICLK and MC1:LOTCMC = 1, TCLK is a buffered (and optionally inverted) version of
RCLK.
5.2 Receive Framer LIU Interface Pins
NAME
I/O
FUNCTION
RPOS/
RNRZ
I
Receive Positive Data Input/Receive NRZ Data Input. If BIN = 0 in the MC1 register, the LIU interface is in
dual-rail (POS/NEG) mode. In this mode, the framer clocks in the serial data stream in AMI format. RPOS =
1 from an external LIU indicates a positive pulse was received on the line; RNEG = 1 from the LIU indicates
a negative pulse was received on the line. If BIN = 1, the framer is in binary (NRZ) LIU interface mode. In
this mode the framer clocks in the serial data stream in binary format on the RNRZ pin. RNRZ = 1 indicates
a 1 in the data stream; RNRZ = 0 indicates a 0 in the data stream. If RCLKI = 0 in the MC5 register, data is
clocked into the framer on the rising edge of RCLK. If RCLKI = 1, data is clocked in on the falling edge of
RCLK. MC5:RPOSI = 1 inverts the polarity of RPOS/RNRZ.
RNEG/
RLCV
I
Receive Negative Data Input/Receive Line-Code Violation Input. If BIN = 0 in the MC1 register, the LIU
interface is in dual-rail (POS/NEG) mode. In this mode, the framer clocks in the serial data stream in AMI
format. RPOS = 1 from an external LIU indicates a positive pulse was received on the line, while RNEG = 1
from the LIU indicates a negative pulse was received on the line. If BIN = 1, the framer is in binary (NRZ) LIU
interface mode. In this mode the framer clocks in the serial data stream in binary format on the RNRZ pin
and line code violations on the RLCV pin. If RCLKI = 0 in the MC5 register, data is clocked into the framer on
the rising edge of RCLK. If RCLKI = 1, data is clocked in on the falling edge of RCLK. MC5:RNEGI = 1
inverts the polarity of RNEG/RLCV. In binary LIU interface mode, when MC5:RNEGI = 0, the BPV counter
(registers BPVCR1 and BPVCR2) counts RCLK cycles when RLCV = 1. When MC5:RNEGI = 1, the BPV
counter counts RCLK cycles when RLCV = 0.
RCLK
I
Receive Clock Input. RCLK is used to clock data into the receive framer on RPOS/RNEG (dual-rail LIU
interface mode) or RNRZ (binary LIU interface mode). If RCLKI = 0 in the MC5 register, data is clocked into
the framer on the rising edge of RCLK. If RCLKI = 1, data is clocked in on the falling edge of RCLK. RCLK is
normally accurate to within ±20ppm when sourced from an LIU, but the framer can also accept a gapped
clock up to 52MHz on RCLK, such as those commonly sourced from ICs that map/demap DS3 and E3
to/from SONET/SDH.
