19-0813; Rev 1; 9/07 EVALUATION KIT AVAILABLE DVI/HDMI TMDS FR-4 and Cable Equalizer/Driver MAX3814 General Description Features The MAX3814 TMDS® EQ/driver IC compensates for Equalizes FR-4 Board Microstrip and Cable HF FR-4 and cable losses up to the DVITM/HDMITM transmit Losses Up to 15dB at 825MHz for Operation at connector and provides a fully compliant DVI/HDMI 0.25Gbps to 1.65Gbps TMDS output. The device can also be used in DVI/HDMIcable applications to extend reach and improve jitter Compatible with HDMI 1.3 margin of cable channels at the receive-side connector. Less Than 0.2UIP-P Residual Jitter at 1.65Gbps for The on-chip TMDS drivers operate at a standard cur- 0 to 15dB Channel Loss at 825MHz rent level for implementing a typical DVI/HDMI non-back-terminated transmitter, as well as a 50% higher Input Terminations: 50 (Each Side to VCC) ±10% current mode for using a 200 back termination resis- Output of Driver is a Fully DVI/HDMI TMDS- tor (nonmatching) to achieve a 10dB return loss.
