LC78625E

• Support for command input from a control microprocessor: commands include track jump, focus start, disk motor

start/stop, muting on/off and track count (8-bit serial input)

• Built-in digital output circuits.

• Arbitrary track counting to support high-speed data access

• D/A converter outputs with data continuity improved by 8× oversampling digital filters. (These filters function as 4×

oversampling filters during double-speed playback.)

• Built-in ∑∆ D/A converter implemented by a third-order noise shaper circuit (for PWM output)

• Built-in digital attenuator (8 bits - alpha, 239 steps)

• Built-in digital de-emphasis circuit that can be controlled externally in some modes

• Zero-cross muting

• Support for 2×-speed dubbing

• Support for bilingual applications

• General-purpose I/O ports: 4 pins (when the antishock mode is turned off)

Features

• 5 V single-voltage power supply

• Low-voltage operation: Can be operated at 3.3 V ±10% (at normal playback speed)

• 80-pin QFP package
