LC89057W-VF4A: Digital Audio Interface Transceiver

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.

特性
  • 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-in PLL error lock prevention circuit to provide accurate lock
