LTC2230/LTC2231

10-Bit,170Msps/

135Msps ADCs

FEATURES

DESCRIPTIO

TheLTC^®2230andLTC2231are170Msps/135Msps,sam-

pling 10-bit A/D converters designed for digitizing high

frequency, wide dynamic range signals. The LTC2230/

LTC2231 are perfect for demanding communications

applicationswithACperformancethatincludes61dBSNR

and 75dB spurious free dynamic range for signals

up to 200MHz. Ultralow jitter of 0.15ps_RMSallows

undersampling of IF frequencies with excellent noise

performance.

and no missing codes over temperature. The transition

■

noise is a low 0.12LSB_RMS

■

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 3.3V.

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

single ended with a sine wave, PECL, LVDS, TTL, or CMOS

inputs. An optional clock duty cycle stabilizer allows high

performance at full speed for a wide range of clock duty

cycles.

170Msps: LTC2220 (12-Bit), LTC2230 (10-Bit)

135Msps: LTC2221 (12-Bit), LTC2231 (10-Bit)
