DS3170N+

Telecom Overview

The DS3170N+ is a single-chip transceiver designed for DS3 and E3 physical copper line interfaces. It integrates a DS3/E3 framer, a Line Interface Unit (LIU), and a jitter attenuator. The device supports receive clock/data recovery and transmit waveshaping. It features an on-chip BERT, HDLC controller with a 256-byte FIFO, and performance-monitoring counters. The component operates at 3.3V with 5V tolerant I/O and consumes approximately 0.5W of power. It utilizes a 100-pin CSBGA package measuring 11mm x 11mm with a 1mm height. The industrial temperature range extends from -40°C to +85°C.

Telecom Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. The plus sign indicates lead-free and RoHS compliant packaging. Confirm that the industrial temperature grade (-40°C to +85°C) matches the design requirements. Ensure the 100-pin CSBGA footprint aligns with the PCB layout specifications before finalizing procurement.

Telecom Selection Notes

Select this component when a combined framer and transceiver solution is required for DS3 or E3 applications. Verify compatibility with the system's microprocessor interface, supporting both 8-bit and 16-bit parallel modes as well as serial SPI. Check if the integrated jitter attenuator placement options suit the network timing architecture. Confirm that the 3.3V power supply and low-power consumption meet the thermal constraints of the enclosure.

Telecom Part Context

The DS3170N+ belongs to the DS3170 family of single-chip transceivers manufactured by Analog Devices / Maxim Integrated. This series provides comprehensive solutions for digital cross-connect systems and multiplexers. The N suffix specifically denotes the industrial temperature rating, distinguishing it from commercial variants. It serves as a core interface component in telecommunications infrastructure requiring high reliability.

Telecom Replacement Considerations

The datasheet notes software compatibility with the DS3171 through DS3174 SCT product family. These devices may serve as functional alternatives within the same ecosystem. Verify register mapping and pinout compatibility before substituting. Consult the manufacturer's errata for any known deviations between revisions.
