GENERAL DESCRIPTION
Performing the tape formatting and error correction functions for DCC applications, the SAA2022 can be used in conjunction with the PASC (SAA2002/SAA2012), tape equalization (SAA2032), read amplifier (TDA1317 or TDA1318) and write amplifier (TDA1316 or TDA1319) circuits to implement a full signal processing system.

FEATURES
• Integrated error correction encoder/decoder function with Digital Compact Cassette (DCC) optimized algorithms
• Control of capstan servo during recording and after recording by microcontroller
• Frequency and phase regulation of capstan servo during playback
• Choice of two Dynamic Random Access Memory (DRAM) types operating in page mode
• Scratch pad RAM area available to microcontroller in system DRAM
• Low power standby mode
• I2S interface
• Microcontroller interface for high-speed transfer burst rates up to 170 kbytes per second
• SYSINFO and AUXILIARY data flags on microcontroller interface
• Protection against invalid AUXILIARY data
• +4 V operating voltage capability.
