The CPU can select www.DataSheet4U.com one of four operating clocks (16.9344-MHz, 75-kHz or 32.768-kHz crystal oscillator and external clock input), facilitating interface with the CD processor. The CD processor incorporates sync separation protection and Weight: 0.32 g (typ.) interpolation, EFM demodulator, error correction, digital equalizer for servo, and servo controller. The CD processor also incorporates a 1-bit DA converter. In combination with the TA2157F/FG/FN/FNG digital servo head amplifier, the TC94A58FAG can very simply configure an adjustment-free CD player. Thus, the IC is suitable for CD systems for automobiles and radio-cassette players.
Features
• • Single-chip CD processor with on-chip CMOS LCD driver and 4-bit microcontroller Operating supply voltage: CD in operation: VDD = 3.0 to 3.6 V (3.3 V typ.) CD stopped: VDD = 1.8 to 3.6 V (only CPU in operation) Supply current: CD in operation: IDD = 30 mA (typ.) CD stopped: IDD = 1.5 mA (CD standby mode, with 16.9344-MHz crystal oscillator, CPU in operation).
