Product Description

The CJC6808 are low power multi route direct sound gathering CODECs. The CJC6808 is also ideal for MD, CD-RW machines and DAT recorders.
The CJC6808 include 6 ADCs and 2 DACs, along with a mute function, programmable line level volume control and a bias voltage output suitable for an electronic microphone. Stereo 24-bit multi-bit sigma delta ADCs and DACs are used with oversampling digital interpolation and decimation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 96kHz are supported. Line level outputs are also provided along with anti-thump mute and power up/down circuitry.

The CJC6808 also include a PLL which can produce 11.2896MHZ clock. Then only 12.288MHZ crystal is needed and we need not change crystal . A sar adc is also put into to wake up the chip when the music coming in .
The device is controlled via a 2 or 3 wire serial interface. The interface provides access to all features including volume controls, mutes, de-emphasis and extensive power management facilities. The smaller 48 lead quad flat leadless package (QFN).
