The DS22EV5110 is a 6.75 Gbps (3 x 2.25 Gbps) extended reach equalizer optimized for DVI™ and HDMI™ cable extension applications with a high performance re-clocking feature. It supports 3 Transition Minimized Differential Signaling (TMDS) data channels and a single clock channel over DVI™ v1.0, and HDMI™ v1.3a data rates up to 2.25 Gbps for each data channel. The device incorporates a configurable receive equalizer, a clock and data recovery (CDR) circuit and a de-emphasis driver on each data channel over DVI v1.0, and HDMI v1.3a data rates up to 2.25 Gbps for each data channel. The device incorporates a configurable receive equalizer with a clock and data recovery (CDR) circuit on each data channel. The clock channel feeds a high-performance phase locked loop (PLL) that regenerates a low jitter output clock for data recovery, enabling the extended reach of driving capability feature for repeater application.

The DS22EV5110 equalizes greater than 25 meters 28 AWG of HDMI cable, enabling 1080p resolution with 12 bit deep color depth (2.25 Gbps), to a low jitter version of the clock and data signal outputs, reducing both deterministic and random jitter. Obtaining total jitter is 0.09 UI or less over the supported data rates. This extremely low level of output jitter provides system designers with extra margin and flexibility when working with stringent timing budgets. It is ideal for the DVI and HDMI source and repeater applications.

The transmitter supports configurable transmit de-emphasis so the output can be optimized for driving additional lengths of cables or FR4 traces.Read more
