SAA7720-TDA1540 (or TDA1541) Audio Format Conversion Driver Module V5 Support Up to 384K/24Bit

Introduction:
- This version of the kernel circuit comes from the first version of TDA1541 384K digital version, which can drive TDA1541 and TDA1540 to play music formats up to 384K/24bit. It is an upgraded version of the previous white version, pin compatible, supports 512FS master clock (jumper can be set), supports I2S with a length of 16 bit, can be directly connected to Raspberry Pi, supports one click NOS/OS switching, supports 16bit/14bit output settings, supports output phase conversion, and supports balanced driving.

Interface Description:
- The J2 input of the module is an I2S signal, while J3 and J4 output a 14bit/16bit signal in Simultaneous format.
- J5 PHASE is the phase setting pin, and a short circuit to GND is the phase reversal.
- J5 NOS is the setting pin for NOS/OS, and a short circuit to GND is considered NOS; Empty as OS.
- S2 sets the switch for NOS/OS, with a short circuit indicating NOS and a disconnection indicating OS; This pin is directly connected to J5 NOS. Please short-circuit S4 S3.
- S1 is the output format setting, short circuited to 14-bit output, which can drive TDA1540; Disconnected to 16-bit, can drive TDA1541.
- S3 is the input MCK frequency setting, mainly for the convenience of SAA7220 use; Short circuit is 512FS, disconnection is 256FS. For example, when the Italian card (for Amanero USB) outputs 512fs MCK at 44.1K 48K, if you want to use SAA7220, set it to S3 short circuit, CPLD will downshift MCK to 256fs to facilitate driving SAA7220.
- J3 outputs a 14bit/16bit L channel signal (including an inverted data signal), while J4 outputs a 14bit channel signal. 16bit R channel signal (including an inverted data signal).
- J1 is a DC 5V power input pin.

Package Included:
- 1 x Format Conversion Driver Module
