1. Overview
The LC89075WA is a digital audio interface receiver that demodulates signals according to the data transfer format between digital audio devices via IEC60958/61937 and JEITA CPR-1205 and supports demodulation sampling frequencies of up to 192k Hz. The LC89075WA also incorporates a high performance 24-bit single-end input stereo analog to digital converter that supports sampling frequencies of up to 96k Hz, and an audio selector that can support 8-channel data. The LC89075WA is a plete analog and digital front-end for use in various systems including AV receivers, digital TVs, and DVD recorders.
