WM8777

24-bit, 192kHz AV Receiver on-a-Chip

DESCRIPTION

FEATURES

•

AV receiver on-a-chip with 8 DACs and 2 ADCs

Integrated S/PDIF/IEC60958/AES3 transceiver

The WM8777 is a high performance, multi-channel audio codec.

The WM8777 is ideal for surround sound processing applications

for home hi-fi, automotive and other audio visual equipment. A

S/PDIF transceiver with 4-channel input mux is included. Analogue

domain bass management processing, and front channel analogue

tone control facilities are provided.

Analogue Bass Management and stereo mixdown support

Analogue tone controls for front 3 channels

Master volume control on each DAC channel with gain range

of +20dB to -100dB in 1dB steps

A stereo 24-bit multi-bit sigma delta ADC is used with a six stereo

channel input selector. Each channel has analogue domain mute

and programmable gain control. Sampling rates from 8kHz to

192kHz are supported.

Audio Performance

−

108dB SNR (‘A’ weighted @ 48kHz) DAC

102dB SNR (‘A’ weighted @ 48kHz) ADC

110dB SNR (‘A’ weighted) Analogue volume control

Four stereo 24-bit multi-bit sigma delta DACs are provided, which

may be used to support up to 7.1 channel operation. If preferred,

5.1 operation may be chosen, with the spare stereo DAC used to

support an Aux remote room. Sampling rates from 8kHz to 192kHz

are supported. Each DAC channel has independent digital volume

and mute control. A set of input multiplexors allows switching of an

external 5.1 analogue input, or bypass channel stereo analogue

input into the signal path. The front channel analogue signals may

be looped out of the chip prior to each master volume control, and

external filtering applied in order to select treble and bass filter

characteristics. Adjustment of tone controls is then achieved using

on-chip gain adjust amplifiers, addressed via the control interface.

Analogue bass management support is provided, plus analogue

stereo mixdown options.

•

DAC Sampling Frequency: 8KHz – 192kHz

ADC Sampling Frequency: 8KHz – 192kHz

3-Wire SPI or 2-wire MPU Serial Control Interface with

readback.

•

Master or Slave Clocking Mode

Programmable Format Audio Data Interface Modes

Four Independent stereo DAC outputs with independent

digital volume controls

•

Integrated Stereo headphone amplifier with source select

5.1 channel analogue input prior to the tone controls, bass

management and stereo mixdown functions.

•

Six stereo input ADC mux with analogue gain adjust from

+24dB to –21dB in 0.5dB steps

The device is controlled via a serial interface giving access to all

features including channel selection, volume controls, tone

controls, mutes, de-emphasis and power management facilities.

The device is available in a 100-pin LQFP package.

5V Analogue, 2.7V to 3.6V Digital supply Operation

APPLICATIONS

•
