WM8803

Digital Audio Interface Receiver

DESCRIPTION

FEATURES

•

PLL circuit for synchronization with transferred input bi-

phase mark signal.

The WM8803 is a digital audio interface receiver conforming

to IEC 60958/61937 and EIAJ CP-1201. It supports input

audio data rates up to 192kHz and a maximum output data

length of 24 bits.

•

Input sampling frequency: 32kHz to 192kHz

Outputs clocks: fs, 64fs, and one of 128fs, 256fs, 384fs,

and 512fs.

The WM8803 has a flexible digital output port that allows the

user access to channel status pre-emphasis information, input

signal sampling frequency, sub-code Q data with the

associated CRC flags and other status data.

•

4-Wire CCB MPU Serial Control or Hardware Default

Interface

•

Master Clocking Mode

The WM8803 can output an externally input clock signal that

can be used as an ADC converter clock when the PLL is

unlocked. It also maintains the continuity of the output clock

when the clock is switched.

Programmable Audio Data Interface Modes

16/20/24/32 bit Word Lengths

•

3.3V Digital supply Operation

5V tolerant digital input ports

The WM8803 includes a built-in oscillator and serial data

input circuits and allows the system micro-controller to read

the sub-code Q data and the channel status. It provides

several low-power modes, thus supporting applications that

require long battery life, such as portable audio devices and

PDAs.

APPLICATIONS

•

DVD Receivers

The device is available in a 24-pin TSSOP package.

DVD-R/W Players

Audio Video Receivers

Portable Music Players
