AD1896AYRSZRL

Overview

The AD1896AYRSZRL is a 24-bit, stereo asynchronous sample rate converter from Analog Devices. It supports input and output sampling frequencies up to 192 kHz with ratios ranging from 7.75:1 downsampling to 1:8 upsampling. The device features a linear phase FIR filter providing up to 142 dB dynamic range (A-weighted) and THD+N performance down to –133 dB. It operates on a 3.3 V core supply and 3.3 V/5 V I/O supplies within an industrial temperature range of –40°C to +105°C. Packaged in a 28-lead SSOP, it includes hardware-controllable soft mute, bypass mode, and multiple serial interface formats.

Feature Summary

• Asynchronous conversion supporting 192 kHz max sample rates and ratios from 7.75:1 to 1:8
• High-performance audio metrics including 142 dB dynamic range and up to –133 dB THD+N
• Flexible 3-wire serial interface supporting Left-Justified, I2S, Right-Justified, and TDM modes
• Hardware-configurable bypass mode and matched-phase mode for multi-chip synchronization

Applications

• Home theater systems
• Studio digital mixers
• Automotive audio systems
• Digital audio effects processors
• Digital tape varispeed applications

Procurement Notes

Verify the ordering suffix 'RL' corresponds to the reel packaging configuration as specified in the manufacturer's ordering guide. Confirm that the component meets RoHS compliance requirements for the intended assembly process. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS circuitry.

Selection Notes

Select this component when asynchronous sample rate conversion between different clock domains is required without software programming. Verify that the system master clock frequency allows for the desired sample rate ratios, noting that maximum sample rates depend on the MCLK input. Ensure the power supply architecture supports separate 3.3 V core and 3.3 V/5 V I/O rails.

Part Context

The AD1896AYRSZRL belongs to the AD1896 series of second-generation asynchronous sample rate converters. It succeeds the AD1890, offering improved jitter rejection and additional serial port formats. The device utilizes a 64-tap FIR filter with 2^20 polyphases to perform interpolation and decimation, ensuring high-fidelity audio processing across varying sample rates.

Replacement Considerations

The AD1896AYRSZ is the tube-packaged equivalent of the AD1896AYRSZRL. Both share identical electrical specifications and pinouts; the distinction lies solely in the shipping packaging format.
