Chrontel’s CH7104B is a low-cost, low-power
semiconductor device that consists of HDMI receiver,
three separate 9-bit video Digital-to-Analog Converters
(DACs), HDTV encoder, and audio encoder, which can
convert HDMI signals into HDTV/VGA 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,
CH7104B supports auto-boot and EDID buffer.
Leveraging the firmware auto loaded from the embedded
flash, CH7104B can support HDMI input detection, DAC
connection detection and determine to enter into Power
saving mode automatically.
