FEATURES
Eight independent, full duplex DS1 Tx and Rx
Framers
Two 512-bit (two-frame) elastic store, PCM frame
slip buffers (FIFO) on TX and Rx provide up to
8.192 MHz asynchronous back plane connections
with jitter and wander attenuation
Supports input PCM and signaling data from 1.544
to 8.192 MHz. Also supports 4-channel multiplexed
12.352/16.384 Mbit/s on the back plane bus
Programmable output clocks for Fractional T1
Supports channel associated signaling (CAS)
Extracts and inserts robbed bit signaling (RBS)
Supports Common-channel and ISDN Primary
Rate Interface (ISDN PRI) signaling
Integrated HDLC controller with two 96-byte Trans-
mit HDLC buffers and two 96-byte Receive HDLC
buffers
Timeslot assignable HDLC
8-bit Intel/Motorola
μ
P interface for configuration,
control and status monitoring
Programmable Interrupt output pin
Supports programmed I/O, Burst and DMA modes
of Read-Write access
Each framer block encodes and decodes the T1
Frame serial data into and from the Single-rail or
Dual-rail (B8ZS) format
Dual or single rail line side digital PCM inputs
Detects and forces Red (SAI), Yellow (RAI) and
Blue (AIS) Alarms
Detects OOF, LOF, LOS errors and COFA condi-
tions
Loopbacks: Local (LLB) and Line remote (LB)
Facilitates Inverse Multiplexing for ATM
Performance monitor with one second polling
Boundary scan (IEEE 1149.1) JTAG test port
Accepts external 8kHz Sync reference
3.3V CMOS operation with 5V tolerant inputs
388-pin BGA package with –40
°
C to +85
°
C opera-
tion
4-channel T1 framer version (XRT84L14) is pin-
compatible with the XRT84V24, 4-channel E1
framer
Direct Interface to Exar’s LIUs: XRT82L38 and
XRT82L34
