LC89052T Overview
ENN7457 CMOS LSI LC89052T Digital Audio Interface Receiver 1. Overview The LC89052T is an audio LSI that demodulates according to the data format for the data transferred between digital audio devices via the IEC 60958/61937 and EIAJ CP-1201. It supports sampling frequencies of up to 192kHz and output data lengths up to 28 bits.
LC89052T Key Features
- Incorporates a built-in PLL circuit to synchronize with transferred bi-phase mark signal
- Can receive input with sampling frequencies of 32kHz to 192kHz
- Can set the upper limit of sampling frequency of received data
- Can receive input data of specific sampling frequencies
- Outputs the following clocks: fs, 64fs, 128fs, 256fs, 384fs, and 512fs
- Contains a built-in oscillation amplifier that can construct a oscillation circuit. An external clock can be also provid
- Outputs an externally input clock signal that can be used as the A/D converter clock when the PLL is unlocked
- Maintains the continuity of the output clock when the clock is switched
- Equipped with a serial digital audio data input pin that can be configured for a demodulated signal output
- Can output up to 28 bits of data, and also supports output of I2S and input NRZ data
