XRT83VSH316

16-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT

REV. 1.0.2

FEATURES

 Fully integrated 16-Channel short haul transceivers for T1/J1 (1.544MHz) and E1 (2.048MHz) applications

 Parallel or SPI Microprocessor Interface

 T1/E1/J1 short haul and clock rate are per port selectable through software without changing components

 Internal Impedance matching on both receive and transmit for 75 (E1), 100 (T1), 110 (J1), and 120

(E1) applications are per port selectable through software without changing components

 Power down on a per channel basis with independent receive and transmit selection

 Five pre-programmed transmit pulse settings for T1 short haul applications per channel

 User programable Arbitrary Pulse mode for T1 and E1

 On-Chip transmit short-circuit protection and limiting protects line drivers from damage on a per channel

basis

 Crystal-Less digital jitter attenuators (JA) with 32-Bit or 64-Bit FIFO for the receive or transmit path per

channel

 Driver failure monitor output (DMO) alerts of possible system or external component problems

 Transmit outputs and receive inputs may be "High" impedance for protection or redundancy applications on a

per channel basis

 Support for automatic protection switching

 1:1 and 1+1 protection without relays

 Receive monitor mode handles 0 to 6dB resistive attenuation (flat loss) along with 0 to 6dB cable loss for

both T1 and E1

 Loss of signal (LOS) according to ITU-T G.775/ETS300233 (E1) and ANSI T1.403 (T1/J1) for system (SLOS)

and line (RLOS) side diagnostics

 Programmable data stream muting upon RLOS detection

 On-Chip HDB3/B8ZS encoder/decoder with an internal 16-bit LCV counter for each channel

 On-Chip digital clock recovery circuit for high input jitter tolerance

 QRSS/PRBS pattern generator and detection for testing and monitoring for system (SPRBS) and line

(PRBS) side diagnostics

 Error and bipolar violation insertion and detection

 Transmit all ones (TAOS) Generators and Detectors for system (SAIS) and line (AIS) side diagnostics

 Supports local analog, remote, digital, and dual loopback modes

 Supports gapped clocks for mapper/multiplexer applications

 1.8V Digital Core

 3.3V I/O and Analog Core

 316-Pin STBGA package

 -40°C to +85°C Temperature Range
