1 / 27 page SM5921A SEIKO NPC CORPORATION —1 8-channel Lip Sync Delay OVERVIEW The SM5921A is an SDRAM controller LSI for audio applications. It stores 64-fs slot 3-wire serial format audio data input at sampling frequency fs in SDRAM, and can access data at an arbitrary address to add a delay to each channel data. It also has a direct mute function to mute the audio data. FEATURES Functions I System clock input 64fs (fs = 32 to 192kHz) bit clock I Sampling frequency: fs = 32 to 192kHz support I Data input/output 3-wire serial, 8-channel PCM 64 clock/slot, word clock polarity inversion I Direct mute function I MCU interface: 3-wire serial I Delay settings: sum of intrinsic delay and individ- ual delay • Intrinsic delay (common to all channels, default = 0 samples, 16-sample units) • Individual delay (independent for each channel, default = 0 samples, 1-sample units) Maximum delay values 1365.3ms @ fs = 48kHz 682.7ms @ fs = 96kHz 341.3ms @ fs = 192kHz I Address shift function: ×1, ×2, ×4 support Delay time can be multiplied between ×1, ×2, or ×4 times without changing the delay set value. I SDRAM interface: 16M/64M/128M ( ×16 devices supported) I Package: 64-pin QFP Structure I Silicon-gate CMOS Applications I Audio delay for multi-channel PCM signals ORDERING INFORMATION PINOUT (Top view) PACKAGE DIMENSIONS (Unit: mm) Weight: 0.35g Note.
