DS3152+

Telecom Overview

The DS3152+ is a dual Line Interface Unit (LIU) designed for physical layer interfacing to DS3, E3, or STS-1 lines. It integrates independent transmit and receive paths with built-in jitter attenuators. The device operates on a single 3.3V power supply with 5V tolerant I/O. It supports hardware mode configuration via pins or CPU bus mode for register access. The component is housed in a 144-pin, 13mm x 13mm thermally enhanced CSBGA package and functions within an industrial temperature range of -40°C to +85°C.

Telecom Feature Summary

• Integrates dual independent transmitter, receiver, and jitter attenuator blocks for DS3, E3, and STS-1 line interfacing.
• Supports both hardware pin configuration and CPU bus interface modes for flexible system integration.
• Includes built-in automatic gain control, adaptive equalizer, and clock/data recovery circuits.
• Provides tri-state outputs for redundancy and protection switching applications.

Telecom Applications

• SONET/SDH and PDH Multiplexers
• Digital Cross-Connect Systems
• Access Concentrators and DSLAMs
• CSUs/DSUs

Telecom Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm the operating temperature range. The 'N' suffix indicates the industrial range (-40°C to +85°C), while the absence of the suffix typically denotes the commercial range (0°C to +70°C). Ensure the package type matches the design requirements before procurement.

Telecom Selection Notes

Select the DS3152+ when two independent LIU ports are required for DS3, E3, or STS-1 interfaces. Compare against the DS3151 (single port) or DS3154 (quad port) based on channel count needs. Verify that the system requires 3.3V operation and 144-pin CSBGA packaging compatibility.

Telecom Part Context

The DS3152+ belongs to the DS315x family of Line Interface Units from Analog Devices Inc./Maxim Integrated. This family includes the DS3151, DS3153, and DS3154 variants, which differ only in the number of integrated LIU ports. All members share identical functional blocks and electrical characteristics.

Telecom Replacement Considerations

Direct replacements include other DS315x variants such as the DS3151, DS3153, or DS3154 if channel count adjustments are acceptable. Verify that the replacement part's temperature rating and package dimensions match the existing board layout.
