Notes
1. Input voltage should not exceed 6.5 V unless otherwise specified.
2. Equivalent to discharging a 100 pF capacitor through a 1.5 kW series resistor.
3. Equivalent to discharging a 200 pF capacitor through a 0 W series resistor.


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 of SAA2022 to implement a full signal processing system.
