The AD1891JP is a 16-bit stereo asynchronous sample rate converter (ASRC) from Analog Devices. It automatically detects input and output sample frequencies between 8kHz and 56kHz and performs sample rate conversion with a ratio of 1:2 to 2:1. The device accepts 16-bit serial audio data via a flexible 4-wire serial interface and does not require external programming for sample rate detection.
The converter operates from a 2.7V to 5.5V supply voltage and is designed for low power consumption. It supports dynamically changing asynchronous sample clocks with smooth transition when frequencies cross. The device includes short/long group delay modes and slow/fast settling modes for optimal clock tracking.
Packaged in a 28-PLCC surface mount package with J-lead terminals (also specified as 28-LCC), the AD1891JP is suitable for compact designs. Typical applications include digital mixing consoles, audio signal routers, CD-R/DAT recorders, studio-to-transmitter links, and digital audio broadcast equipment.
The AD1891JP operates from 2.7V to 5.5V supply voltage.
The AD1891JP is available in a 28-PLCC (11.51x11.51) surface mount package with J-leads.
The AD1891JP is listed as RoHS3 compliant, though this is unverified at present.
The AD1891JP supports input and output sample rates from 8 kHz to 56 kHz.
The AD1891JP is a stereo converter with two channels.
The AD1891JP uses a flexible 4-wire serial interface.
The AD1891JP supports input to output sample clock ratios from 1:2 to 2:1.
