PCB still needs layout for one more time. The Si570 clock board GB version should be V3.0 .

I'll figure out the reversed MCLK issue, reversing or delaying.

Hi Ian,
Will you be including the TPS7A4700 reg board for the Si570 module? Sure interested in it.

Thanks

Default External controller is possible for Si570 clock board now

Si570 driver will partly open frequency control to third party external controller from a UART. The footprint of UART isolator is also reserved on the isolator board. Here is the protocol:

//Si570 multi-frequency clock board serial communication protocol V1.0 2012-11-03 by Ian
//USART 9600,n,8,1

//events sent from si570 driver
//Format: 0xAA,EVENT,DATA,0x55
//EVENTS:
#define GETNEWFS 0xC1 //FIFO detected a new Fs which need a new MCLK frequency
#define SETFRQ 0xC2 //new Si570 frequency is set
#define SETXFS 0xC3 //new xfs is set
#define WRONGINPUTCMD 0xC4 //wrong input commend or no input command
#define WRONGINPUTFRQ 0xC5 //input frequency is overange
#define INVALIDINPUTFRQ 0xC6 //input frequency is invalid for current Fs


//Command response from external controller
//Format: 0xA5,CMD,DATA,0x5A
//0xC8 command has to be sent within 100ms after getting event 0xC1,
//Otherwise Si570 driver will determine the setting frequency and xfs according to the preset without stop the music
//CMD:
#define TOINPUTFRQ 0xC8 //set frequency for the new detected Fs by external controller

//sample frequency data of event 0xC1,
//#define FS22 0
//#define FS24 1
//#define FS44 2
//#define FS48 3
//#define FS88 4
//#define FS96 5
//#define FS174 6
//#define FS192 7
//#define FS352 8
//#define FS384 9

//xfs data for event 0xC3
//#define XFS256 0
//#define XFS512 1
//#define XFS1024 2
//#define XFS2048 3

//frequency data for event 0xC2 and command 0xC8
//#define F112896 0
//#define F122880 1
//#define F225792 2
//#define F245760 3
//#define F451584 4
//#define F491520 5
//#define F903168 6
//#define F983040 7
