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.
Applications
• Twisted-pair drivers
• Differential line drivers
• VGA over twisted-pair
• Transmission of analog signals in a noisy environment
Ordering Information
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.
