LC89052TA-E Datasheet | SANYO

.Data Sheet.co.kr Ordering number : ENN7457A 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 192k Hz and output data lengths up to 28 bits. Despite it is pact 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 32k Hz to 192k Hz. - 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. - 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. - Can output bi-phase mark signal synchronized with the 128fs bit clock. - Provides an output pin for the channel status bit 1 non-PCM data detection bit. - Provides an output pin for the channel status emphasis detection bit. - Supports a lower-power mode. - Calculates the input signal sampling...
