DS3163

Specialized ICS Overview

The DS3163 is a triple ATM/Packet PHY transceiver integrating three independent ports for mapping and demapping ATM cells or HDLC packets into DS3, E3, or clear-channel data streams. It operates within a 0°C to +70°C temperature range and utilizes a 400-pin TE-PBGA package (27mm x 27mm). The device supports UTOPIA L2/L3, POS-PHY L2/L3, and SPI-3 interfaces with configurable bus widths of 8, 16, or 32 bits. Each port features dedicated cell and packet processors, on-chip DS3/E3 framers, and built-in HDLC controllers with 256-byte FIFOs for overhead insertion and extraction.

Specialized ICS Feature Summary

Specialized ICS Procurement Notes

Verify the specific ordering suffix when purchasing. The standard DS3163 indicates a commercial temperature range of 0°C to +70°C. The 'N' suffix denotes an industrial grade (-40°C to +85°C). A '+' suffix indicates a lead-free package option. Confirm the package type is 400 TE-PBGA (27mm x 27mm, 1.27mm pitch) to ensure mechanical compatibility with existing designs.

Specialized ICS Selection Notes

Select the DS3163 specifically for triple-port requirements; single, dual, and quad variants are available as DS3161, DS3162, and DS3164 respectively. All variants in the family are pin-compatible, facilitating density migration on the same PCB platform. Ensure interface requirements match UTOPIA, POS-PHY, or SPI-3 standards. Verify thermal constraints against the commercial (DS3163) or industrial (DS3163N) temperature ratings.

Specialized ICS Part Context

The DS3163 belongs to the DS316x family, which includes single (DS3161), dual (DS3162), and quad (DS3164) configurations. These devices share identical pinouts and software compatibility, allowing for flexible design scaling. The series integrates ATM/Packet PHY functions with DS3/E3 framing, serving as a system-on-chip solution for high-density line cards in telecommunications infrastructure.

Specialized ICS Replacement Considerations

The DS3163 is pin and software compatible with the DS3181–DS3184 series (which include built-in LIUs) and the DS3171–DS3174 series (single-chip transceivers with framers and LIUs). When replacing, verify that the target application does not require integrated Line Interface Units (LIUs), as the DS3163 provides only PHY and framer functions.
