The HI5865 is designed with a fully differential pipelined
architecture using a front end differential-in-differential-out
Sample-and-Hold amplifier (S/H). The HI5865 has excellent
dynamic performance while consuming 450mW of power at
65 MSPS.
Data output latches are provided which present valid data to
the output bus with a low data latency of 9 clock cycles.
