Chrontel’s CH7107B is a low-cost, low-power

semiconductor device that consists of HDMI receiver,

three separate 9-bit video Digital-to-Analog Converters

(DACs), SDTV encoder and audio encoder, which can

convert HDMI signals into SDTV outputs with IIS or

SPDIF audio output.

The HDMI Receiver integrated is compliant with HDMI

1.4b. With sophisticated MCU and the on-chip flash,

CH7107B supports auto-boot and EDID buffer.

Leveraging the firmware auto loaded from the embedded

flash, CH7107B can support HDMI input detection, DAC

connection detection and determine to enter into Power

saving mode automatically.
