Overview
19-0298; Rev 4; 5/96 KIT ATION EVALU ABLE AVAIL 6-Bit Quadrature Digitizer _______________General Description The MAX2101 6-bit quadrature digitizer combines quadrature demodulation with analog-to-digital conversion on a single bipolar silicon die.
This unique RF-to-Bits TM function bridges the gap between existing RF downconverters and CMOS digital signal processors (DSPs).
The MAX2101’s simple receiver subsystem is designed for digital communications systems such as those used in DBS, TVRO, WLAN, and other applications.
The MAX2101 accepts input signals from 400MHz to 700MHz and applies adjustable gain, providing at least 40dB of dynamic range.
Each baseband is filtered by an on-chip, 5th-order Butterworth lowpass filter, or the user can select an external filter path.
Baseband sample rate is 60Msps.
The MAX2101 is available in a commercial temperature range, 100-pin MQFP package.
