LC89057W-VF4A-E

Ordering number : EN7202A LC89057W-VF4A-E CMOS IC Digital Audio Interface Transceiver http://onsemi.com 1. Overview The LC89057W-VF4A-E is an audio IC that demodulates and modulates signals according to data transfer format between digital audio devices via the IEC60958/61937 and EIAJ CP-1201 and supports up to 192kHz of sampling frequency. It features a built-in VCO and oscillation amplifier, two bit clock circuits that are capable of setting independently the frequency-dividing ratios that can also be used for the DSP data input/output clocks, and LR clock output pins. A multi-channel PCM interface using multiple LC89057W-VF4A-E ICs is also available through a master/slave function. This IC is optimal for use in high performance AV amplifiers and a multi-channel PCM interface for DVD audio equipment. 2. Features 2.1 Realizes full demodulation for high performance AV equipment Possible to receive the sampling frequency of 32kHz to 192kHz and 24 bits data at a maximum. Supports I2S data output that facilitates interfacing with DSP. Output clock: 512fs, 256fs, 128fs, 64fs, 32fs, 2fs, fs, and fs/2 Possible to output oscillation amplifier and external input clocks regardless of the PLL status. Maintains output clock continuity during clock switching. Supports Multi-channel transfer and reception, using master/slave function. Possible to process demodulation functions using common low-jitter clock without using PLL (external clock synchronization function) Built...
