FEATURES

DESCRIPTION

70dB SNR

TheLTC^®2152-14/LTC2151-14/LTC2150-14are250Msps/

210Msps/170Msps 14-bit A/D converters designed for

digitizing high frequency, wide dynamic range signals.

They are perfect for demanding communications applica-

tions with AC performance that includes 70dB SNR and

90dB spurious free dynamic range (SFDR). The 1.25GHz

input bandwidth allows the ADC to undersample high

frequencies with good performance. The latency is only

six clock cycles.

90dB SFDR

Low Power: 356mW/338mW/313mW Total

Single 1.8V Supply

DDR LVDS Outputs

Easy-to-Drive 1.5V Input Range

P-P

1.25GHz Full Power Bandwidth S/H

Optional Clock Duty Cycle Stabilizer

Low Power Sleep and Nap Modes

Serial SPI Port for Conﬁguration

Pin Compatible 12-Bit Versions

40-Pin (6mm × 6mm) QFN Package

DCspecsinclude 0.85LSBINL(typ), 0.25LSBDNL(typ)

and no missing codes over temperature. The transition

noise is 1.82LSB

RMS

The digital outputs are double-data rate (DDR) LVDS.

APPLICATIONS

–

The ENC and ENC inputs can be driven differentially with

asinewave,PECL,LVDS,TTL,orCMOSinputs.Anoptional

clock duty cycle stabilizer allows high performance at full

speed for a wide range of clock duty cycles.
