LTC2222-11

11-Bit, 105Msps ADC

FEATURES

DESCRIPTIO

The LTC^®2222-11 is a 105Msps, sampling 11-bit A/D

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2222-11 is perfect for

demanding communications applications with AC perfor-

mance that includes 65.4dB SNR and 80dB spurious free

dynamic range for signals up to 150MHz. Ultralow jitter of

0.15ps_RMSallows undersampling of IF frequencies with

excellent noise performance.

noise is a low 0.25LSB_RMS

■

Data Ready Output Clock

■

A separate output power supply allows the CMOS output

swing to range from 0.5V to 3.3V.

Pin Compatible Family

135Msps: LTC2224 (12-Bit), LTC2234 (10-Bit)

105Msps: LTC2222 (12-Bit), LTC2232 (10-Bit)

80Msps: LTC2223 (12-Bit), LTC2233 (10-Bit)

48-Pin 7mm × 7mm QFN Package

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.
