GENERAL DESCRIPTION
The SAA2023 performs the drive processor function in the
DCC system. This function is built up of digital equalizer,
error correction and tape formatting functions. The digital
equalizer is intended for use with DCC read amplifiers
TDA1318 or TDA1380. The tape formatting and error
correction circuit is intended for use with PASC ICs
SAA2003 and SAA2013, and write amplifiers TDA1319 or
TDA1381.
