The data and clock inputs are the most critical paths for
the MAX3815 and great care should be taken to mini-
mize discontinuities on these transmission lines
between the connector and the IC. Here are some sug-
gestions for maximizing the performance of the
MAX3815:
• The data and clock inputs should be wired directly
between the cable connector and IC without stubs.

The exposed pad on the 48-pin TQFP-EP provides a
very low thermal resistance path for heat removal from
the IC. The pad is also electrical ground on the
MAX3815 and must be soldered to the circuit board
ground for proper thermal and electrical performance.
