Preliminary speciﬁcation

Masking threshold processor for MPEG

layer 1 audio compression applications

SAA2521

FEATURES

• Stereo or 2-channel mono encoding

• Status may be read continuously

• Microcontroller interface

• I2S-interfaces

• Allocation algorithm including optional emphasis

correction (for 44.1 kHz)

• Reduced power consumption

• 4 V nominal operating voltage capability.

GENERAL DESCRIPTION

The SAA2521 performs the adaptive allocation and

scaling function for calculating the masking thresholds and

sub-band sample accuracy in MPEG layer 1 applications.

The SAA2521 is intended for use in conjunction with the

stereo filter codec SAA2520.
