LTC2265-14/

LTC2264-14/LTC2263-14

14-Bit, 65Msps/40Msps/

25Msps Low Power Dual ADCs

FEATURES

DESCRIPTION

The LTC

2265-14/LTC2264-14/LTC2263-14 are 2-channel,

simultaneous sampling 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 73.7dB SNR and

90dB spurious free dynamic range (SFDR). Ultralow jitter

of 0.15ps

RMS

allows undersampling of IF frequencies with

excellent noise performance.

DC specs include ±1LSB INL (typ), ±0.3LSB DNL (typ)

and no missing codes over temperature. The transition

noise is a low 1.2LSB

RMS

The digital outputs are serial LVDS to minimize the num-

ber of data lines. Each channel outputs two bits at a time

(2-lane mode) or one bit at a time (1-lane mode). The LVDS

drivers have optional internal termination and adjustable

output levels to ensure clean signal integrity.

The ENC

and ENC

–

inputs may be driven differentially

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

CMOS inputs. An internal clock duty cycle stabilizer

allows high performance at full speed for a wide range of

clock duty cycles.
