AD1892JR

Overview

The AD1892JR is an integrated digital receiver and asynchronous sample rate converter manufactured by Analog Devices Inc. It combines a CP-1201, CP-340, IEC-958, AES/EBU, and S/PDIF compatible Digital Audio Receiver with a SamplePort architecture-based rate converter. The device operates on a single +5 V supply within the industrial temperature range of -40 °C to +85 °C. Key electrical specifications include a dynamic range of 120 dB and a THD+N of -113 dB at 1 kHz. It supports input word widths up to 20 bits and output word widths of 16 or 20 bits. The package is a 28-lead SOIC.

Feature Summary

• Integrates a digital audio receiver supporting multiple serial transmission standards including S/PDIF, AES/EBU, and IEC-958.
• Features an asynchronous sample rate converter utilizing SamplePort technology for superior jitter rejection.
• Includes hardware buffers for Q-channel subcode and channel status information with CRC calculation capabilities.
• Provides flexible three-wire serial data port configurations supporting left-justified, right-justified, and I2S modes.

Applications

• DVD, DAT, MD, DCC and CD-R recorders and players
• Computer multimedia products
• DAB receivers and automotive digital audio networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel options. Confirm that the component meets all required environmental and regulatory standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a combined digital reception and sample rate conversion function is required in a compact form factor. Ensure the system design accommodates the 28-lead SOIC package dimensions and provides the necessary master clock frequency synchronous with the desired output sample rate.

Part Context

This part belongs to the AD1892 family of integrated digital receivers and rate converters from Analog Devices. It is designed for high-performance consumer and professional audio applications requiring robust clock recovery and jitter attenuation capabilities within a single integrated circuit solution.

Replacement Considerations

The AD1892JRRL is a verified alternative offering the same functional specifications but packaged on 13-inch reels instead of standard tubes.
