• Normal mode

The Normal is data input mode from CD,MD,DVD etc.

Input pins are DATA,BCK, and LRCK.

• External 8fs Data mode

In this mode, the 8fs rate data inputted from external device.

Input pins are EXDATAL,EXDATAR,EXBCK and EXWCK.

The data synchronized with the clock of EXBCK,EXWCK pins are inputted into EXDATAL,EXDATAR pins .

Selectable "Input for primary side synchronization" and "Input for secondary side synchronization"

by the serial control System1 mode bit21(EXMODE)

In the case of primary side synchronization, the data inputted to the Sampling Rate Converter block.

In the case of secondary side synchronization, the data inputted to Gain Control block.

• SACD-fsi mode

In this mode, SACD format data inputted.

Input pins are DSDL,DSDR,DSD128Fs and DSD64Fs.

The clock of a Down Sampling Filter is given from a *primary side, and down sampled data are

inputted into the Sampling Rate Converter block.

The data synchronized with the clock of DSD128Fs,DSD64Fs pins are inputted into DSDL,DSDR pins.

• SACD-fso mode

In this mode, SACD format data inputted.

Input pins are DSDL,DSDR,DSD128Fs and DSD64Fs.

The clock of a Down Sampling Filter is given from a *secondary side, and down sampled data are

inputted into the Gain Control block.

The data synchronized with the clock of DSD128Fs,DSD64Fs pins are inputted into DSDL,DSDR pins.

* primary clock: This clock means input side clock System of the sampling rate converter.

secondary clock: This clock means output side clock System of the sampling rate converter. The block after Sampling

Rate Converter ( Gain Control Block,

.∆Σ Block, and PWM Block) operate with secondary clock

"fsi", "fso", and "fs" are defined as follows in this data sheet.

fsi: The primary side Sampling Frequency

fso: The secondary side Sampling Frequency

fs: The sampling frequency which can be set as both by the side of primary and secondary .

(External 8fs Data , SACD Data etc.)
