The CS8427 is a stereo digital audio transceiver with AES3 and serial digital audio inputs, AES3 and serial digital audio outputs, and includes comprehensive control ability through a 4-wire microcontroller port. Channel status and user data are assembled in block-sized buffers, making read/modify/write cycles easy. A low-jitter clock recovery mechanism yields a very clean recovered clock from the incoming AES3 stream. Target applications include A/V receivers, CD-R, DVD receivers, multimedia speakers, digital mixing consoles, effects processors, set-top boxes, and computer and automotive audio systems.
The CS8427 is a stereo digital audio transceiver supporting AES3, S/PDIF, and IEC‑60958 formats. It offers low‑jitter clock recovery, flexible 3‑wire serial control, and both microcontroller and standalone operation for applications such as A/V receivers, DVD players, and digital mixers.
The manual contains a full set of specifications, electrical characteristics, pin‑out diagrams, register maps, timing diagrams, and application notes. It also includes switching characteristics, PLL filter design guidance, and revision history for the device.
| Power Supply Voltage VA+ (min/typ/max) | 4.5 V / 5.0 V / 5.5 V |
|---|---|
| Power Supply Voltage VL+ (min/typ/max) | 2.85 V / 3.30 V / 5.0 V / 5.5 V |
| Ambient Operating Temperature (CS/CSZ/CZ) | -10 °C to +70 °C |
| Supply Current at 96 kHz frame rate (VA+) | 6.6 mA typ |
| RMCK output jitter | 200 ps RMS |
VA+ must be between 4.5 V (minimum) and 5.5 V (maximum), with a typical value of 5.0 V.
The device operates from –10 °C up to +70 °C for the CS/CSZ/CZ versions (‑40 °C to +85 °C for the DS/DZ versions).
Power‑down mode is entered by setting RST low while keeping all clocks and data lines static.
The typical supply current is 6.6 mA when VA+ is powered at 5 V.
