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. Despite it is compact and made in a low cost, the LC89052T 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.
