• Manufacturer Part Number: evm6435
• Description: Per-pin Electronics Companion
• Manufacturer: Semtech Corporation

The E6435/E6436 can be configured to provide all of the
DAC levels required for 4 fully-featured high-speed pin
channels or 8 fully-featured low-speed pin channels when
used with other Semtech pin electronics components.
Since each E6435/E6436 DAC channel includes 2 sets
of calibration registers, DAC channels can be shared across
two distinct functions in an application to minimize the
overall number of level DACs required in a system. Tables
5 and 6 show the recommended shorting scheme for a
couple of possible pin electronics solutions.
