3 Description
The ISO7821LLS device is a high-performance,
isolated dual-LVDS buffer with 8000-V_PK isolation
voltage. This device provides high electromagnetic
immunity and low emissions at low-power
consumption, while isolating the LVDS bus signal.
Each isolation channel has an LVDS receive and
transmit buffer. Timing performance for the
ISO7821LLS device is optimized for use with
communication systems that use DC-balanced data
streams which is achieved through an internal
distortion correction scheme.
The ISO7821LLS device has one forward and one
reverse-direction channel.
Through innovative chip design and layout
techniques, the electromagnetic compatibility of the
ISO7821LLS device has been significantly enhanced
to ease system-level ESD, EFT, surge, and
emissions compliance.
The ISO7821LLS device is available in a 16-pin SOIC
wide-body (DW) and extra-wide body (DWW)
packages.
