LC89075WA: Digital Audio Interface Receiver with Stereo ADC and Audio Selector
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 192kHz. The LC89075WA also incorporates a high performance 24-bit single-end input Delta-Sigma stereo analog to digital converter that supports sampling frequencies of up to 96kHz, and an audio selector that can support 8-channel data. The LC89075WA is a complete analog and digital front-end for use in various systems including AV receivers, digital TVs, and DVD recorders.
