Overview

The LC8900KQ is a CMOS LSI circuit chip that can be used to enable the EIAJ CP-1201 formatted data transmission between digital audio equipment. It is used by the receiving end and operates synchronously with input signals. This chip demodulates input signals into normally-formatted signals.

Features

? On-chip PLL circuit: enables the LSI operation to be synchronous to the transmitted EIAJ format input signals.

? Four input pins and one output pin: The output pin enables the input data to be sent as they are.

? Two data output function modes: 20-bit data LSB first mode and 16-bit data MSB first mode.

? Four output clocks: Bit clock, LRCK, 384Fs and 256Fs.

All these clocks are synchronized to the data.

? Various signal outputs: copy inhibit, emphasis on:off control, user’s bit, validity flag and sampling frequency.

? LPF time constant select mode: This function can be used in the PLL lock-up state.

? Error detect signal output: If an input data error is detected, this LSI circuit chip outputs the error signal.

In this case, the previous data will be output by the chip.

? Lock-up signal output: This signal is output when the internal PLL (Phase Locked Loop) block of the LSI circuit chip is locked.

? The chip has the pin to receive a signal for stopping the PLL operation.

? Control and processing mode via microcontroller interface: input pin select, copy information and sampling frequency output.

? Each input pin has an internal amplifier circuit.

? Si gate, CMOS process technology and single 5V power supply applicational and functional concept.
