ISL59311

Differential Video Amplifier with Common

Mode Sync Encoder and Serial Digital

Interface

The ISL59311 is a high bandwidth triple differential amplifier

with integrated encoding of video sync signals. The inputs

are suitable for handling high speed video or other

communications signals in either single-ended or differential

form, and the common-mode input range extends all the way

to the negative rail enabling ground-referenced signaling in

single supply applications. The high bandwidth enables

differential signaling onto standard twisted-pair or coax with

very low harmonic distortion, while internal feedback

ensures balanced gain and phase at the outputs reducing

radiated EMI and harmonics.

Embedded logic encodes standard video horizontal and

vertical sync signals onto the common mode of the twisted

pair(s), transmitting this additional information without the

requirement for additional buffers or transmission lines. The

ISL59311 enables significant system cost savings when

compared with discrete line driver alternatives.

The digital block of the chip is a data transceiver which is

intended to drive one twisted pair line. The maximum

baudrate for this block is 50Mbps.

The ISL59311 is available in a 32 Ld QFN package and is

specified for operation over the -40°C to +85°C temperature

range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100% matte

tin plate termination finish, which are RoHS compliant and compatible

with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
