28-Lead SOIC Package

The AD1892 combines a CP-1201, CP-340, IEC-958, AES/

EBU, S/PDIF compatible Digital Audio Receiver (DAR) with

an asynchronous sample rate converter, allowing the user to

specify the output sample rate of the received digital audio infor-

mation. The DAR block features support for both Q-channel

subcode information (to support CD, CD-R, MD and DAT

digital audio formats) as well as Channel Status information. A

microcontroller interface, with an SPI compatible serial port,

allows full access to the 80-bit Q-Channel subcode buffer and to

the 32-bit Channel Status buffer, as well as to the control and

status registers. Additionally, key status information from the

incoming subframes and the Channel Status buffer is reported

on status output pins on the AD1892, so the AD1892 may be

used in systems that do not include a microcontroller or

microprocessor.

The asynchronous sample rate converter block is based on

market leading AD1890 family SamplePort rate conversion tech-

nology. The AD1892 offers a 1:5 upsampling range, and will

downsample from 48 kHz to 44.1 kHz. Input audio word widths

up to 20 bits are supported, and output audio word widths of 16

or 20 are supported, with 120 dB of dynamic range and –113 dB

THD+N. The rate converter inherently rejects jitter on the

recovered clocks from the incoming biphase-mark encoded

stream. Indeed, sample rate conversion is highly synergistic

with digital audio reception, allowing the use of a fully digital

phase locked loop clock recovery scheme with highly robust

clock recovery and jitter rejection.
