LTC2242-12

12-Bit, 250Msps ADC

FEATURES

DESCRIPTION

The LTC^®2242-12 is a 250Msps, sampling 12-bit A/D con-

verterdesignedfordigitizinghighfrequency,widedynamic

range signals. The LTC2242-12 is perfect for demanding

communications applications with AC performance that

includes 65.4dB SNR and 78dB SFDR. Ultralow jitter of

Sample Rate: 250Msps

65.4dB SNR

78dB SFDR

1.2GHz Full Power Bandwidth S/H

Single 2.5V Supply

Low Power Dissipation: 740mW

performance.

LVDS, CMOS, or Demultiplexed CMOS Outputs

Selectable Input Ranges: 0.5V or 1V

DC specs include 1.0LSB INL (typ), 0.4LSB DNL (typ)

and no missing codes over temperature.

No Missing Codes

Optional Clock Duty Cycle Stabilizer

The digital outputs can be either differential LVDS, or

single-ended CMOS. There are three format options for

the CMOS outputs: a single bus running at the full data

rate or two demultiplexed buses running at half data rate

witheitherinterleavedorsimultaneousupdate. Aseparate

output power supply allows the CMOS output swing to

range from 0.5V to 2.625V.

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 over a wide range of clock duty cycles.
