DESCRIPTION

The LTC

verter designed for digitizing high frequency, wide dynamic

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

95fs

performance.

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

and no missing codes over temperature.

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

with either interleaved or simultaneous update. A separate

output power supply allows the CMOS output swing to

range from 0.5V to 2.625V.

The ENC

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.
