IT6692FN Single Chip HDMI to VGA Converter with Embedded MCU Preliminary Datasheet ITE TECH. INC. www.ite.com.tw Mar-2012 Rev:0.81 1/11 IT6692FN General Description The IT6692FN is a high-performance single-chip HDMI to VGA converter. Combined with HDMI 1.3 receiver and triple DACs, the IT6692FN supports HDMI input and VGA output by conversion function. The build-in HDMI receiver is fully compliant with HDMI 1.3a specification. With HDMI 1.3a receiver, the IT6692FN can support resolutions up to Full HD ( 1080P ), WUXGA and UXGA. Also the build-in triple DACs can support up to 10 bit deep colors. The single chip IT6692FN provides high performance, cost effective, HDMI2VGA conversion function, and it can help modern NBs like ultrabooks and tablets to be compatible with traditional VGA only projectors, monitors, and TVs. With Embedded MCU and Flash, IT6692FN is easy to program thru the ISP interface. Customers need no external Flash and MCU to save the BOM cost and board size.
