Maxim MAX3814CHJ+

线缆均衡3V ~ 3.6V表面贴装型

Overview

The MAX3814CHJ 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. The on-chip TMDS drivers operate at a standard current level for implementing a typical DVI/HDMI nonback-terminated transmitter, as well as a 50% higher current mode for using a 200Ω back termination resistor (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. The 4-channel implementation treats all channels identically. To allow board layout flexibility for DVI and HDMI connectors, which have different channel order, the clock and data channels can be arbitrarily assigned. The MAX3814CHJ 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.
