DESCRIPTION

DESCRIPTION

TYPE(1)

I/O

NO.

PWRDN

PWRDN powers down all logic and stops all clocks whenever logic high is

applied. However, the coefficient memory remains stable through a power

down cycle, as long as a reset is not sent after a power down cycle.

Pulldown

REGULATOR_EN

REGULATOR_EN is only used in factory tests. This pin should always be tied

to ground.

None

RST

RST is the master reset input. Applying a logic low to this pin generates a

master reset. The master reset results in all coefficients being set to their

power-up default state, all data memories being cleared, and all logic signals

being returned to their default values.

Pullup

SCLKIN

SCLKIN is the serial audio port (SAP) input data clock. This clock is only used

when the SAP is a slave. In master mode, SCLKOUT1 internally provides the

serial input clock (SCLKOUT1 from a given TAS3103 must not be connected

to SCLKIN on the same TAS3103 chip).

Pulldown

SCLKOUT1

SCLKOUT1 is one of two serial output bit clocks. It is divided from

MCLKI/XTALI in master mode, and SCLKIN in slave mode. Subaddress

control fields determine the divide ratio in both cases. When the serial audio

port is in a master mode, SCLKOUT1 is used to receive incoming serial data

and should be wired to the data source(s) providing data to the SDIN inputs.

None

SCLKOUT2

SCLKOUT2 is one of two serial output bit clocks. It is divided from

MCLKI/XTALI in master mode, and SCLKIN in slave mode. Subaddress

control fields determine the divide ratio in both cases. SCLKOUT2 is always

used to clock out serial data from the three serial SDOUT output data

channels. SCLKOUT2 is provided separately from SCLKOUT1 to allow

discrete in to TDM out and TDM in to discrete out data format conversions

without the use of external glue logic.

Output

SDIN1

SDIN1, SDIN2, SDIN3, and SDIN4 are the four TAS3103 serial data input

ports. All four input ports support four discrete (stereo) data formats. SDIN1 is

the only data input port that also supports eleven time division multiplexed

data formats. All four ports are capable of receiving data with bit rates up to

24.576 MHz.

Pulldown

SDIN2

SDIN2 is one of the four TAS3103 serial data input ports. SDIN2 supports four

discrete (stereo) data formats, and is capable of receiving data with bit rates

up to 24.576 MHz.

Pulldown

SDIN3

SDIN3 is one of the four TAS3103 serial data input ports. SDIN4 supports four

discrete (stereo) data formats, and is capable of receiving data with bit rates

up to 24.576 MHz.

Pulldown

SDIN4

SDIN4 is one of the four TAS3103 serial data input ports. SDIN4 supports four

discrete (stereo) data formats, and is capable of receiving data with bit rates

up to 24.576 MHz.

Pulldown

SDOUT1

SDOUT1, SDOUT2, and SDOUT3 are the three TAS3103 serial data output

ports. All three output ports support four discrete (stereo) data formats.

SDOUT1 is the only data output port that also supports eleven time division

multiplexed data formats. All three ports are capable of outputting data at bit

rates up to 24.576 MHz.

None

SDOUT2

SDOUT2 is one of the three serial data output ports. SDOUT2 supports four

discrete (stereo) data formats, and is capable of outputting data at bit rates up

to 24.576 MHz.

None

SDOUT3

SDOUT3 is one of the three serial data output ports. SDOUT3 supports four

discrete (stereo) data formats, and is capable of outputting data at bit rates up

to 24.576 MHz.

None

TEST

TEST is only used in factory tests. This pin must be left unconnected or

grounded.
