描述 Description

Chrontel’s CH7105B 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 CVBS/S-Video/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, CH7105B supports auto-boot and EDID buffer. Take the advantage of Firmware auto loaded from the embedded flash, CH7105B can support HDMI input detection, DAC connection detection and determine to enter into SDTV mode or VGA mode or Power saving mode automatically.
