9 / 58 page DS685F1 9 CS42435 2. PIN DESCRIPTIONS - HARDWARE MODE Pin Name # Pin Description TEST 1,2,4 Test - These pins are inputs used for test purposes only. They must be tied high or low. MFREQ 3 MCLK Frequency (Input) - Sets the required frequency range of the input master clock. RST 5 Reset (Input) - The device enters a low-power mode and all internal registers are reset to their default settings when low. VLC 6 Control Port Power (Input) - Determines the required signal level for the control port interface. See “Digital I/O Pin Characteristics” on page 8. FS 7 Frame Sync (Input) - Signals the start of a new TDM frame in the TDM digital interface format. VD 8 Digital Power (Input) - Positive power supply for the digital section. DGND 9,18 Digital Ground (Input) - Ground reference for the digital section. VLS 10 Serial Port Interface Power (Input) - Determines the required signal level for the serial port inter- faces. See “Digital I/O Pin Characteristics” on page 8. SCLK 11 Serial Clock (Input) - Serial clock for the serial audio interface. Input frequency must be 256 x Fs. MCLK 12 Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters. ADC_SDOUT 13 Serial Audio Data Output (Output) - TDM output for two’s complement serial audio data. DAC_SDIN 14 DAC Serial Audio Data Input (Input) - TDM Input for two’s complement serial audio data. AUX_LRCK 15 Auxiliary Left/Right Clock (Output) - Determines which channel, Left or Right, is currently active on the Auxiliary serial audio data line. AUX_SCLK 16 Auxiliary Serial Clock (Output) - Serial clock for the Auxiliary serial audio interface. AUX_SDIN 17 Auxiliary Serial Input (Input) - The 42435 provides an additional serial input for two’s comple- ment serial audio data.
