FEATURES

DESCRIPTION

TheLTC^®2268-12/LTC2267-12/LTC2266-12are2-channel,

simultaneous sampling 12-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 70.6dB SNR and

88dB spurious free dynamic range (SFDR). Ultralow jitter

2-Channel Simultaneous Sampling ADC

DC specs include 0.ꢀLSB INL (typ), 0.1LSB DNL (typ)

and no missing codes over temperature. The transition

Pin Compatible 14-Bit and 12-Bit Versions

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). At lower sampling rates there is a one bit

per channel option (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 al-

lows high performance at full speed for a wide range of

clock duty cycles.
