LC89052TA-E

www.DataSheet.co.kr Ordering number : ENN7457A LC89052TA-E 1. Overview CMOS IC Digital Audio Interface Receiver The LC89052TA-E 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. Despite it is compact and made in a low cost, the LC89052TA-E includes a built-in oscillator and serial data input circuits and allows the system microcontroller to read the sub-code Q data and channel status. It supports low-power modes that allow low-voltage operation. It also supports a lower power mode, which is suitable for application that requires long battery life, such as cell phones, PDAs, and portable audio devices. 2. 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 provided. 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. Equ...
