Abstract: The MAX3645 is a pin-for-pin replacement of the Mindspeed MC2045-2 and MC2045-2Y post-amplifiers. Critical performance advantages of the MAX3645 include stable LOS (loss-of-signal) assert/deassert levels over the supply range, stable LOS hysteresis over the programmable levels, and better sensitivity. External component values need to be adjusted for the replacement design. This design note provides typical data that can be used to determine new external component values.
