Input
CS42L73 MCLK1 external master clock connection
- By default, Y1 oscillator is populated and used for MCLK1.
- Remove Y1 oscillator before connecting external master clock.
Input
CS42L73 MCLK2 external master clock connection
Input/Output
CS42L73 Audio Serial Port (LRCK, SCLK, SDIN, SDOUT)
- By default, shunts connect the columns marked “BOARD.” This connects the
CS42L73 Audio Serial port to the S/PDIF interface.
- To use external clock and data signals, remove shunts. Connect external sig-
nal and ground to columns marked “EXT CONN.”
Input/Output
CS42L73 Voice Serial Port (LRCK, SCLK, SDIN, SDOUT)
Input/Output
CS42L73 Auxiliary Serial Port (LRCK, SCLK, SDIN, SDOUT)
Input/Output
CS42L73 control port connections (SDA, SCL, INT, RESET)
- By default, shunts connect the columns marked “BOARD.” This connects the
microcontroller to the control port of the CS42L73.
- To use external control signals, remove shunts. Connect external signal and
ground to columns marked “EXT CONN.”
