DS2152L

Telecom Overview

The DS2152L is an enhanced T1 single-chip transceiver manufactured by Analog Devices Inc./Maxim Integrated. It provides complete DS1 and ISDN-PRI transceiver functionality for both long-haul and short-haul trunks. The device features a 32-bit or 128-bit crystal-less jitter attenuator, generates DSX-1 and CSU line build-outs, and frames to D4, ESF, and SLC-96 formats. It includes dual on-board two-frame elastic store slip buffers connecting to asynchronous backplanes up to 8.192MHz. The unit operates on a 5V supply with low-power CMOS technology and is housed in a 100-pin, 14mm LQFP package.

Telecom Feature Summary

• Complete DS1/ISDN-PRI transceiver functionality supporting long- and short-haul trunks
• Crystal-less jitter attenuation with selectable 32-bit or 128-bit depth
• Dual on-board two-frame elastic store slip buffers for asynchronous backplane connections
• 8-bit parallel control port compatible with multiplexed or nonmultiplexed Intel or Motorola buses

Telecom Applications

• T1 digital carrier systems
• ISDN Primary Rate Interface (PRI) applications
• Telecommunications network interface units

Telecom Procurement Notes

Verify the specific suffix of the part number to confirm the operating temperature range before procurement. The 'L' suffix indicates a commercial range of 0°C to +70°C, while the 'LN' suffix denotes an industrial range of -40°C to +85°C. Confirm RoHS compliance status based on the '+' designation if required for the assembly process.

Telecom Selection Notes

Select the DS2152L when a software-selectable T1 transceiver with integrated framer and line interface is required. Ensure the system design accommodates the 5V supply voltage and utilizes the 100-pin LQFP footprint. Consider the DS2152LN variant if the application environment requires operation at temperatures below 0°C or above 70°C.

Telecom Part Context

The DS2152L belongs to the Maxim Integrated Enhanced T1 Single-Chip Transceiver family. It serves as a superset version of the DS2151, retaining original features while adding hardware signaling capabilities, per-channel code insertion, and independent transmit/receive elastic stores. It is pin-compatible with the DS2154 E1 Enhanced Single-Chip Transceiver.

Telecom Replacement Considerations

The DS2152L+ is the lead-free/RoHS-compliant equivalent of the standard DS2152L. For industrial temperature requirements, the DS2152LN or DS2152LN+ should be considered. Verify that any replacement maintains compatibility with the 100-LQFP package and 5V logic levels.
