of SCLK and is ignored when SE is low.
Serial Data Input of the Codec. Both data and control information may be input on this pin and are
clocked on the negative edge of SCLK . SDI is ignored when SE is low.
SPORT Enable. Asynchronous input enable pin for the SPORT . When SE is set low by the DSP, the
output pins of the SPORT are three-stated and the input pins are ignored. SCLK is also disabled
internally in order to decrease power dissipation. When SE is brought high, the control and data
registers of the SPORT are at their original values (before SE was brought low), however the timing
counters and other internal registers are at their reset values.

Analog Output from the Positive T erminal of the Output Channel.
Analog Output from the Negative T erminal of the Output Channel.
Analog Power Supply Connection for the Output Driver.
Analog Ground Connection for the Output Driver.
Analog Input to the Positive T erminal of the Input Channel.
Analog Input to the Negative T erminal of the Input Channel.
Buffered Reference Output, which has a nominal value of 1.2 V or 2.4 V, the value being dependent
on the status of Bit 5VEN (CRC:7).
A Bypass Capacitor to AGND2 of 0.1 μF is required for the on-chip reference. T he capacitor should
be fixed to this pin.
Analog Power Supply Connection.
Analog Ground/Substrate Connection.
Digital Ground/Substrate Connection.
Digital Power Supply Connection.
Active Low Reset Signal. T his input resets the entire chip, resetting the control registers and clearing
the digital circuitry.
Output Serial Clock whose rate determines the serial transfer rate to/from the codec. It is used to
clock data or control information to and from the serial port (SPORT ). T he frequency of SCLK is
equal to the frequency of the master clock (MCLK ) divided by an integer number—this integer
number being the product of the external master clock rate divider and the serial clock rate divider.
Master Clock Input. MCLK is driven from an external clock signal.
Serial Data Output of the Codec. Both data and control information may be output on this pin and is
clocked on the positive edge of SCLK . SDO is in three-state when no information is being
transmitted and when SE is low.
Framing Signal Output for SDO Serial T ransfers. T he frame sync is one-bit wide and it is active one
SCLK period before the first bit (MSB) of each output word. SDOFS is referenced to the positive
edge of SCLK . SDOFS is in three-state when SE is low.
Framing Signal Input for SDI Serial T ransfers. T he frame sync is one-bit wide and it is valid one
SCLK period before the first bit (MSB) of each input word. SDIFS is sampled on the negative edge
