This document is about SAA2023, a drive processor for DCC systems. It is an integrated circuit with low power consumption, single chip digital equalizer, tape formatting and error correction
The document is a preliminary specification for the Philips SAA2023, an integrated circuit designed as a drive processor for Digital Compact Cassette (DCC) systems. Released in May 1994, it serves as a target or goal specification for product development rather than a final release.
The chip integrates functions such as digital equalization, tape formatting, and error correction into a single unit. Key features include an 8-bit flash analog-to-digital converter (ADC), switchable Infinite Impulse-Response (IIR) filter sections, and programmable Finite Impulse-Response (FIR) filters for main data channels. It also supports both DRAM and SRAM types for system memory and includes a microcontroller interface.
| Operating supply voltage | 4.5 to 5.5 V |
|---|---|
| Low power dissipation | 260 mW at 5.0 V |
| ADC type | 8-bit flash analog-to-digital converter |
| Clock input frequency | 24.576 MHz |
The device operates with a supply voltage between 4.5 and 5.5 V.
The chip dissipates 260 mW when supplied with 5.0 V.
Pin 16, labeled CLK24, requires a 24.576 MHz clock input.
