MAXIM INTEGRATED / ANALOG DEVICES DS21348TN Line Interface Module
The DS21348TN+ from Maxim Integrated is a 3.3V line interface device supporting E1 and T1 protocols, encased in a 44-pin TQFP package. It provides a complete, selectable interface for both short-haul and long-haul applications, with automatically adjustable receive sensitivity. Programmable gain settings range from 0dB to 12dB or 43dB for E1, and 0dB to 30dB or 36dB for T1. The device can generate G.703 E1 waveforms for 75-ohm or 120-ohm configurations, and supports line build-outs for DSX-1 or CSU connections, with attenuation options of 0dB, -7.5dB, -15dB, or -22.5dB for T1. It features a crystal-less jitter attenuator that requires only a 2.048MHz master clock for both protocols. The jitter attenuator includes a FIFO buffer with selectable depth of 32 or 128 bits, configurable for transmit or receive paths. An output clock synthesized to RCLK provides a system clock for backplane applications. The device operates from a 3.3V power supply, with a 50mA RMS current limit, and supports an operating temperature range from -40°C to 85°C. It includes encoding and decoding capabilities for AMI, HDB3, and B8ZS, various clock outputs, programmable monitor modes, loopback and PRBS pattern testing with error detection, in-band loop codes, and both parallel and serial interfaces with hardware modes. Additional features include transmit open-circuit detection, support for Intel or Motorola bus standards, and alarm detection for blue (AIS) signals.
