Description
• Sampling Rate . . . . . . . . . . . . . . . . . . . . . . . . . 65 MSPS 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
• Low Power at 65 MSPS . . . . . . . . . . . . . . . . . . . .450mW
• Internal Sample and Hold
• Fully Differential Architecture
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.
• Full Power Input Bandwidth . . . . . . . . . . . . . . . 250MHz
• Low Data Latency
• TTL Compatible Clock Input
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.
• CMOS Compatible Digital Data Outputs
Applications
• Multichannel Digital Communication Receivers
• Cellular/PCS Basestation Receivers
• Undersampling Digital IF
Data output latches are provided which present valid data to
the output bus with a low data latency of 9 clock cycles.
• Digital Subscriber Line (VDSL)
• Medical Ultrasound
