IT6251
LVDS to DispalyPort 1.1a Transmitter
Preliminary Datasheet Specification V0.2
ITE TECH. INC.
General Description
The IT6251 is a high-performance single-chip De-SSC LVDS to DisplayPort converter. Combined with LVDS receiver and DisplayPort Transmitter, the IT6251 supports LVDS input and DisplayPort 1.1a output by conversion function. The build-in LVDS receiver can support single-link and dual-link LVDS inputs, and the build-in DisplayPort transmitter is fully compliant with DisplayPort 1.1a specification. With high speed LVDS RX, the IT6251 can support resolution up to 1080P and UXGA and 10-bit deep colors.
In order to reduce the EMI noise on legacy system application, the traditional LVDS source will transmit differential signals with spread spectrum, but this spread spectrum does not be allowed for DisplayPort protocol. The IT6251 also build-in unique De-SSC ( De-Spread Spectrum ) function , it can help customers easily to adopt the IT6251 on the EMI-concerned platform, with SSC has been generated from LVDS source processors.
