Clock Input/Crystal Oscillator Pin.
Provides support for parallel resonant AT cut crystals. A 4.9152 MHz crystal or a
4.9152 or 27 MHz clock on XTALI is required.
Crystal Oscillator Pin.
Serves as the output of the crystal amplifier.
Clock output in serial mode. Active low read/write enable for SPI EEPROM in
serial mode when pin 4 is pulled low during powerup. Address Enable in parallel
mode.
Frame Sync/Data Bit.
Frame Sync output to codec in serial mode. Bidirectional parallel bus data bit 6 in
parallel mode.
Digital Supply Voltage.
Provides the 3.3 V supply voltage to the Si2457/34/15/04.
Ground.
Connects to the system digital ground.
Regulator Voltage Reference.
Connects to an external capacitor and serves as the reference for the internal
voltage regulator.
Request to Send/Data Bit.
Active low request to send input used for flow control in serial mode. Bidirectional
parallel bus data bit 7 in parallel mode.
Receive Data/Read Enable.
Data output to DTE RXD pin in serial mode. Active low read enable pin in parallel
mode.
