- AN9214, Using Harris High Speed A/D Converters
The HI5865 is a monolithic, 12-bit, 65 MSPS Analog-to-
Digital Converter fabricated in an advanced CMOS
process. It is designed for high speed, high resolution appli-
cations where wide bandwidth, low power consumption and
excellent SINAD performance are essential. With a
250MHz full power input bandwidth and high frequency
accuracy, the converter is ideal for many types of
communication systems employing digital IF architectures.
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.
