interconnection of the function block data and clocks.

• DVD/CD RECORDERS

The DIR and DIT are compatible with the AES3,

standards. The audio serial ports, DIT, and SRC may

be operated at sampling rates up to 216kHz. The DIR

lock range includes sampling rates from 20kHz to

216kHz.

The SRC4382 is configured using on-chip control

registers and data buffers, which are accessed

through either a 4-wire serial peripheral interface

(SPI) port, or a 2-wire Philips I2C bus interface.

Status registers provide access to a variety of flag

and error bits, which are derived from the various

function blocks. An open drain interrupt output pin is

provided, and is supported by flexible interrupt

reporting and mask options via control register

settings. A master reset input pin is provided for

initialization by a host processor or supervisory

functions.

The SRC4382 requires a +1.8V core logic supply, in

addition to a +3.3V supply for powering portions of

the DIR, DIT, and line driver and receiver functions. A

separate logic I/O supply supports operation from

+1.65V to +3.6V, providing compatibility with low

voltage logic interfaces typically found on digital

signal processors and programmable logic devices.

The SRC4382 is available in a lead-free, TQFP-48

package, and is pin- and register-compatible with the

Texas Instruments SRC4392 and DIX4192 products.
