LC89058W-E

Ordering number : ENA1056A LC89058W-E CMOS IC Digital Audio Interface Receiver http://onsemi.com 1. Overview The LC89058W-E is a digital audio interface receiver IC that demodulates signals according to a data transfer format between digital audio devices via the IEC60958/61937 and JEITA CPR-1205. It supports demodulation sampling frequencies of up to 192kHz. The LC89058W-E can easily replace the existing LC89057W-VF4A-E. The LC89058W-E incorporates a number of features for its low cost and is optimal for receiving digital data for AV amplifiers and receivers. 2. Features 2.1 Clock Built-in PLL false lock prevention circuit to provide accurate lock. Includes built-in oscillation amplifier and frequency divider for quartz resonator. Output clock: 512fs, 256fs, 128fs, 64fs, 32fs, 16fs, 2fs, fs, 1/2fs, and 1/4fs. Possible to set the oscillation amplifier (external input) clock output regardless of the PLL status. Generates transition period signal for switching between the PLL clock and oscillation amplifier (external input) clock. Allows the user to set the PLL clock output frequency for each sampling frequency band of input data. 2.2 Data Can receive S/PDIF and serial data at sampling frequencies of 32kHz to 192kHz. Equipped with a total of 7 digital data input pins: 1 input pin with an amplifier and 6 input pins with 5V tolerable TTL level signal. Can generate data to be demodulated and through output data separately from a maximum of 7 kinds of S/PDIFs. ...
