DVI/HDMI TMDS FR-4 and

Cable Equalizer/Driver

MAX3814

General Description

Features

♦ Equalizes FR-4 Board Microstrip and Cable HF

Losses Up to 15dB at 825MHz for Operation at

0.25Gbps to 1.65Gbps

The MAX3814 TMDS EQ/driver IC compensates for

FR-4 and cable losses up to the DVI™/HDMI™ transmit

connector and provides a fully compliant DVI/HDMI

TMDS output. The device can also be used in DVI/HDMI

cable applications to extend reach and improve jitter

margin of cable channels at the receive-side connector.

♦ Compatible with HDMI 1.3

♦ Less Than 0.2UI

Residual Jitter at 1.65Gbps for

P-P

The on-chip TMDS drivers operate at a standard cur-

rent level for implementing a typical DVI/HDMI non-

back-terminated transmitter, as well as a 50% higher

current mode for using a 200Ω back termination resis-

tor (nonmatching) to achieve a 10dB return loss.

Typical DVI/HDMI output drivers contribute to reflection

problems between the connector and a typical high-

impedance (open) DVI/HDMI Tx output. The selectable

output current (LEVEL pin) gives the option of partial

back termination (e.g., differentially connected 200Ω) to

mitigate the reflection problem effectively while keeping

common-mode offset to a minimum.

0 to 15dB Channel Loss at 825MHz

♦ Input Terminations: 50Ω (Each Side to V ) 10ꢀ

♦ Output of Driver is a Fully DVI/HDMI TMDS-

Compatible Cable Driver

♦ Output Amplitude: 1.05V

Differential

P-P

♦ Enable Pin to Select Normal Operation or Power-

Down Mode

♦ LEVEL Pin to Select Output Current for Use With

or Without Back Termination

The 4-channel implementation treats all channels identi-

cally. To allow board layout flexibility for DVI and HDMI

connectors, which have different channel order, the

clock and data channels can be arbitrarily assigned.

♦ 32-Pin TQFP for Four Channels; Any Channel Can

Be Either a TMDS Data or Clock Signal

♦ V

= 3.3V; Signal Pins Have Absolute Max

Ratings of 5.5V (for Fault Conditions)

The MAX3814 operates from a 3.3V power supply,

standard for DVI/HDMI applications, and is packaged

in a 5mm x 5mm x 0.1mm, 32-pin TQFP package.
