LC89058W-E
CMOS IC
Digital Audio Interface Receiver
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.

Figure 7.4 Change from LC89058W-E to LC89057W-VF4A-E (when the INT pin is set to pull-down)
• It is necessary to review the circuit pattern of the printed circuit board to change the pull-up resistor of pin 35 to the
pull-down resistor because pins 44 to 47 is used as general purpose I/O input function.
• It is necessary to review the circuit pattern of the printed circuit board because the I/O setting of pin 48 differs from
each other.
• After the replacement, the RXOUT2 output of LC89057W-VF4A-E cannot be used.

• After the replacement, pins 44 to 47 can be used as general purpose I/O output function. However, it is necessary to
review the circuit pattern of printed circuit board because pin 48 has to GND.
• After the replacement, the RXOUT2 output of LC89057W-VF4A-E cannot be used.
