RST  
I
Reset. A high-low-high transition clears all internal registers and reset both algo-  
rithms. The device should be reset on system power-up, and/or when changing  
to/from hardware mode.

VSS  
XIN  
I
Signal Ground. 0.0 volts  
X Data In. Samples on falling edge of CLKX during selected timeslots.  
CLKX  
I
X Data Clock. Data clock for X side PCM interface; must be coherent and rising  
edge aligned with FSX.

FSY  
Y Data Out. Updated on rising edge of CLKY during selected timeslots.  
Y Frame Sync. 8 KHz frame sync for Y side PCM interface.  
CLKY  
I
Y Data Clock. Data clock for Y side PCM interface; must be coherent and rising  
edge aligned with FSY.

YIN  
I
Y Data In. Samples on falling edge of CLKY during selected timeslots.  
Positive Supply. 5.0 volts.

should also be asserted when changing to/from the  
HARDWARE RESET  
RST allows the user to reset both channel algorithms  
and register contents. This input must be held low for at  
least 1 ms on system power-up after master clock is  
stable to assure proper initialization of the device. RST  
hardware mode. RST clears all bits of the control regis-  
ter except IPD; IPD is set for both channels, powering  
down the device.
