kr Ordering number : EN7202A LC89057W-VF4A-E 1.
Overview CMOS IC 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.
