IT66318
产品详情
IT66318 is a single in, single out HDMI 2.0 retiming buffer that supports a signaling rate of up to 6.0 Gbps. It is compliant to the latest HDMI 2.0a specification and backward compatible to HDMI 1.4 specification. With 6.0 Gbps capability, IT66318 can support ultra-high resolution content stream, such as 4K x 2K@60Hz format. At extremely high data rate like this, signal quality drops significantly with extended board trace or cable length, making an additional retiming buffer necessary in many systems.
The IT66318 equalizes incoming TMDS signal to optimal and outputs retimed data to downstream sinks. The highly acclaimed equalization technology of ITE TECH. INC. provides for support of long or low quality on board PCB trace at even the highest speeds. Input terminations of the TMDS inputs and output terminations and current levels are both detachable and programmable.
Active DDC buffer is employed in IT66318 to completely isolate downstream DDC loading from upstream source, without addecting communication on the DDC bus, including backward Read Request feature defined in HDMI 2.0.
With embedded MCU and Flash, IT66318 can be easily program med through the ISP interface. The integrated MCU controls IT66318 by itself thus reducing customer development and programming efforts and saving the BOM cost and board size with no external processors needed.
