120
E1 twisted pair cable and 75 E1 coaxial cable
applications
!
Per-channel configurable Line Interface options
Supports various line interface options
– Differential and Single Ended line interfaces
– true Single Ended termination on primary and secondary side of trans-
former for E1 75
coaxial cable applications
– transformer-less for Differential interfaces
Fully integrated and software selectable receive and transmit
termination
– Option 1: Fully Internal Impedance Matching with integrated receive
termination resistor
– Option 2: Partially Internal Impedance Matching with common external
resistor for improved device power dissipation
– Option 3: External impedance Matching termination
Supports global configuration and per-channel configuration to
E1 mode
!
Per-channel programmable features
Provides E1 short haul waveform templates and user-
programmable arbitrary waveform templates
Provides two JAs (Jitter Attenuator) for each channel of receiver
and transmitter
Supports AMI/HDB3 encoding and decoding
!
Per-channel System Interface options
Supports Single Rail, Dual Rail with clock or without clock and
sliced system interface
Integrated Clock Recovery for the transmit interface to recover
transmit clock from system transmit data
!
Per-channel system and diagnostic functions
Provides transmit driver over-current detection and protection
with optional automatic high impedance of transmit interface
Detects and generates PRBS (Pseudo Random Bit Sequence),
ARB (Arbitrary Pattern) and IB (Inband Loopback) in either
receive or transmit direction
Provides defect and alarm detection in both receive and transmit
directions.
– Defects include BPV (Bipolar Violation) /CV (Code Violation) and EXZ
(Excessive Zeroes)
– Alarms include LLOS (Line LOS), SLOS (System LOS), TLOS
(Transmit LOS) and AIS (Alarm Indication Signal)
Programmable LLOS detection /clear levels. Compliant with ITU
and ANSI specifications
Various pattern, defect and alarm reporting options
– Serial hardware LLOS reporting (LLOS, LLOS0) for all 22 channels
– Configurable per-channel hardware reporting with RMF/TMF
(Receive /Transmit Multiplex Function)
– Register access to individual registers or 16-bit error counters
Supports Analog Loopback, Digital Loopback and Remote
Loopback
Supports T1.102 line monitor
!
Channel 0 monitoring options
Channel 0 can be configured as monitoring channel or regular
channel to increase capacity

Monitoring of any of the 21 channels of receiver or transmitter
Jitter Measurement per ITU O.171
!
Hitless Protection Switching (HPS) without external Relays
Supports 1+1 and 1:1 hitless protection switching
Asynchronous hardware control (OE, RIM) for fast global high
impedance of receiver and transmitter (hot switching between
working and backup board)
High impedance transmitter and receiver while powered down
Per-channel register control for high impedance, independent for
receiver and transmitter
!
Clock Inputs and Outputs
Flexible master clock (N x 2.048 MHz) (1
≤ N ≤ 8, N is an integer
number)
Two selectable reference clock outputs
– from the recovered clock of any of the 22 channels
– from external clock input
– from device master clock
Integrated clock synthesizer can multiply or divide the reference
clock to a wide range of frequencies: 8 KHz, 64 KHz, 2.048 MHz,
4.096 MHz, 8.192 MHz, 19.44 MHz and 32.768 MHz
Cascading is provided to select a single reference clock from
multiple devices without the need for any external logic
!
Microprocessor Interface
