1 Introduction

The Device Supports a Primary as well as Secondary ASI. There are several automatic modes of operation described where either the primary BCLK /FYSNC or Secondary BCLK/FSYNC can be used for determination of the incoming timing modes.

In addition, the MCLK / FSYNC can also be used to do the timing determination.

The device has the following interfaces that setup the clocking.

Interface Setup
MCLK Master Clock
FSYNC Primary FSYNC/ Secondary SYNC
PASI BCLK Primary BCLK
PASI FSYNC Primary FSYNC
SASI BCLK Secondary BCLK
SASI FSYNC Secondary SYNC

The BCLK and FSYNC Pins as well as the GPIO/GPI/GPO pins can be configured to setup the Primary and Secondary ASI.

The timings must lie within the limits described in Table 1-1 and Table 1-2.

BCLK 235.2KHz – 22.57MHz
MCLK 235.1KHz - 45.15MHz
Note: The nomenclature of Target is used to indicate Slave Mode of Operation. The nomenclature of Controller is used to indicate Master Mode of operation.
