SINGLE-CHANNEL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. 1.0.1
FEATURES
Fully integrated single-channel short-haul transceiver for E1,T1 or J1 applications
Programmable Transmit Pulse Shaper for E1,T1 or J1 short-haul interfaces
Five fixed transmit pulse settings for T1 short-haul applications plus a fully programmable waveform
generator for transmit output pulse shaping
High receiver interference immunity
Receive monitor mode handles 0 to 29dB resistive attenuation along with 0 to 6dB of cable attenuation for
both T1 and E1 modes
Supports 75 and 120 (E1), 100 (T1) and 110 (J1) applications.
Internal and/or external impedance matching for 75,100, 110 and 120.
Tri-State transmit output and receive input capability for redundancy applications
Provides High Impedance for Tx and Rx during power off
Transmit return loss meets or exceeds ETSI 300 166 standard
On-chip digital clock recovery circuit for high input jitter tolerance
Crystal-less digital jitter attenuator with 32-bit or 64-bit FIFO Selectable either in transmit or receive path
On-chip frequency multiplier generates T1 or E1 Master clocks from variety of external clock sources
On-chip transmit short-circuit protection and limiting, and driver fail monitor output (DMO)
Receive loss of signal (RLOS) output
On-chip HDB3/B8ZS/AMI encoder/decoder
QRSS pattern generation and detection for testing and monitoring
Error and Bipolar Violation Insertion and Detection
