General Description
The CS8427 is a stereo digital audio transceiver with
AES3 and serial digital audio inputs, AES3 and serial
digital audio outputs, and includes comprehensive con-
trol ability through a 4-wire microcontroller port. Channel
status and user data are assembled in block-sized buff-
ers, 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 au-
tomotive audio systems.

1. CHARACTERISTICS AND SPECIFICATIONS
All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical per-
formance characteristics and specifications are derived from measurements taken at nominal supply voltages and
TA = 25°C.
SPECIFIED OPERATING CONDITIONS
AGND, DGND = 0 V, all voltages with respect to 0 V.

Notes: 1. I²C protocol is supported only in VL+ = 5.0 V mode.
ABSOLUTE MAXIMUM RATINGS
AGND, DGND = 0 V; all voltages with respect to 0 V. Operation beyond these limits may result in permanent dam-
age to the device. Normal operation is not guaranteed at these extremes.

* A separate analog supply is only necessary in applications where RMCK is used
for a jitter sensitive task. For applications where RMCK is not used for a jitter
sensitive task, connect VA+ to VD+ via a ferrite bead. Keep the decoupling
capacitor between VA+ and AGND.
