LTC2220/LTC2221

12-Bit,170Msps/

135Msps ADCs

FEATURES

DESCRIPTIO

TheLTC^®2220andLTC2221are170Msps/135Msps,sam-

pling 12-bit A/D converters designed for digitizing high

frequency, wide dynamic range signals. The LTC2220/

LTC2221 are perfect for demanding communications

applications with AC performance that includes 67.5dB

SNR and 80dB spurious free dynamic range for signals

up to 170MHz. Ultralow jitter of 0.15ps_RMSallows

undersampling of IF frequencies with excellent noise

performance.

Pin Compatible Family

The digital outputs can be either differential LVDS, or

single-ended CMOS. There are three format options for

theCMOSoutputs:asinglebusrunningatthefulldatarate

or two demultiplexed buses running at half data rate with

either interleaved or simultaneous update. A separate

output power supply allows the CMOS output swing to

range from 0.5V to 3.6V.

The ENC⁺and ENC^–inputs may be driven differentially or

singleendedwithasinewave, PECL, LVDS, TTL, orCMOS

inputs. An optional clock duty cycle stabilizer allows high

performance at full speed for a wide range of clock duty

cycles.
