1. Overview
The LC89058W-E is a digital audio interface receiver IC that demodulates signals according to a data transfer format
between digital audio devices via the IEC60958/61937 and JEITA CPR-1205. It supports demodulation sampling
frequencies of up to 192kHz. The LC89058W-E can easily replace the existing LC89057W-VF4A-E.
The LC89058W-E incorporates a number of features for its low cost and is optimal for receiving digital data for AV
amplifiers and receivers.
2. Features
2.1 Clock
• Built-in PLL false lock prevention circuit to provide accurate lock.
• Includes built-in oscillation amplifier and frequency divider for quartz resonator.
• Output clock: 512fs, 256fs, 128fs, 64fs, 32fs, 16fs, 2fs, fs, 1/2fs, and 1/4fs.
• Possible to set the oscillation amplifier (external input) clock output regardless of the PLL status.
• Generates transition period signal for switching between the PLL clock and oscillation amplifier (external input)
clock.
• Allows the user to set the PLL clock output frequency for each sampling frequency band of input data.
2.2 Data
• Can receive S/PDIF and serial data at sampling frequencies of 32kHz to 192kHz.
• Equipped with a total of 7 digital data input pins: 1 input pin with an amplifier and 6 input pins with 5V tolerable
TTL level signal.
• Can generate data to be demodulated and through output data separately from a maximum of 7 kinds of S/PDIFs.
• Equipped an S/PDIF input data detection function. Possible to monitor the data input status of 32kHz to 192kHz
with
microcontroller.
