"ET2154 is compatible with DS2154

ET2154 is an E1 PCM_30/ISDN-PRI transceiver, the single-chip integrates the LIU and E1 Framer. The device completely meets the ITU-T specifications, including G. 703, G. 704, G. 706, and G. 823.

Description
The on-chip clock/data recovery circuit in the receive path converts the AMI/HDB3 E1 signal to a NRZ serial E1 stream. The receive sensitivity is -12dB, which meets the short distance transmission from 0 to 1000m. The transmit path can generate the G. 703 waveforms for both 75-ohm COAX and 120-ohm twisted cables. The jitter attenuator can be placed in either transmit or receive paths, the restraint for the jitter meets the specification G. 823 and G. 705.
The framer locates the frame and multi-frame and monitors the data stream for alarms. The ET2154 is also used for extracting and inserting signaling data, Si and Sa bits.

Features
The LIU receive path recovers the data and clock, decodes HDB3, and attenuates the clock jitter. The LIU transmit path completes coding HDB3, generating E1 pulse and driving line.
The framer can receive and transmit data independently, support the E1 frame formats including CRC4, FAS, and CAS.

The functions of E1 framer:
Frames or de-frames CRC4, FAS, and CAS formats.
Extracts and inserts CAS signaling data, Sa and Si bits of CRC4 multi-frame.
Detects and generates Remote and AIS alarms.
Provides programmable output clock for fractional E1, H0, H12 applications.
Counters for bipolar polarity or code violations, CRC4 codeword errors, FAS errors and E bits errors.
Provides 4 read and write modes of CPU interface, including INTEL or MOTOROLA multiplexed and non- multiplexed bus.
Provides 4 separate test loopbacks.
5V supply, 100 pins 14mm*14mm LQFP package.
