AD2437KCPZY-RL

Overview

The AD2437KCPZY-RL is a consumer-grade A2B transceiver from Analog Devices Inc., packaged in a 48-LFCSP (7x7) with Tape & Reel delivery. It provides multichannel I2S/TDM links over distances up to 30 meters between nodes, embedding bidirectional synchronous PCM data, clock, and synchronization signals onto a single-pair differential cable. The device supports up to 51 channels of 16-bit data or 32 channels of 24-bit data. It operates within a supply voltage range of 1.7V to 1.98V and functions at junction temperatures between 0°C and 105°C.

Feature Summary

• Supports up to 51 channels of 16-bit or 32 channels of 24-bit data transmission
• Enables communication over distances up to 30m between nodes via single-pair differential cable
• Integrates PDM interface for up to 4 high dynamic range microphones
• Configurable as main or subordinate node with I2C/SPI programmability

Applications

• Audio Systems
• Musical Instruments

Procurement Notes

Verify the specific ordering suffix KCPZY-RL corresponds to the 48-WFQFN Exposed Pad package and Tape & Reel format. Confirm that the component meets the specified 0°C to 105°C operating temperature range and 1.7V to 1.98V supply voltage requirements for the intended design environment.

Selection Notes

Select this transceiver for applications requiring robust digital audio networking with low latency. Ensure the system design accommodates the 48-LFCSP footprint and utilizes the supported interfaces including GPIO, I2C, I2S, PDM, SPI, and TDM. Verify compatibility with the required power supply constraints and thermal management for the specified operating temperature range.

Part Context

This component belongs to the AD2437 series of A2B transceivers designed for professional and consumer audio applications. It facilitates distributed audio architectures by allowing multiple nodes to connect in a daisy-chain topology, supporting both bus-powered and locally powered configurations within the same network.
