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, supporting both long-haul and short-haul trunks. The device features a 32-bit or 128-bit crystal-less jitter attenuator and generates DSX-1 and CSU line build-outs. It frames to D4, ESF, and SLC-96 formats and includes dual on-board two-frame elastic store slip buffers for asynchronous backplanes up to 8.192MHz. Powered by a 5V supply with low-power CMOS technology, it is housed in a 100-pin, 14mm LQFP package.

Telecom Feature Summary

• Complete DS1/ISDN-PRI transceiver functionality with independent transmit and receive paths
• Crystal-less jitter attenuation with selectable 32-bit or 128-bit depth
• Integrated HDLC controller with 16-byte buffers for the Facility Data Link (FDL)
• Supports D4, ESF, and SLC-96 framing formats with programmable in-band loop code generation

Telecom Applications

• T1 digital carrier systems
• ISDN Primary Rate Interface (PRI) applications
• Short-haul and long-haul trunk connections
• Asynchronous backplane interfaces

Telecom Procurement Notes

Verify component authenticity through authorized distributors or Analog Devices channels. Confirm the lead-free/RoHS-compliant status indicated by the '+' suffix. Check for specific revision errata via official documentation before integration into new designs.

Telecom Selection Notes

Select this model for applications requiring full T1 compliance with flexible bus interface options. Ensure the system supports the required 5V supply voltage. Consider the 100-pin LQFP footprint constraints during PCB layout design.

Telecom Part Context

This component belongs to the DS2152 series of enhanced T1 single-chip transceivers. It serves as a superset to the DS2151, retaining original features while adding hardware signaling capabilities and per-channel monitoring functions within the same pin-compatible package.

Telecom Replacement Considerations

The DS2152L is the non-RoHS equivalent. The DS2154 is a pin-compatible E1 variant. Verify software compatibility when migrating from the DS2151 base model.
