DESCRIPTIO

All other trademarks are the property of their respective owners.

*LTC2220-1, LTC2220, LTC2221, LTC2230, LTC2231 are 3.3V parts.

The LTC

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2242-12 is perfect for

demanding communications applications with AC perfor-

mance that includes 65.4dB SNR and 78dB SFDR. Ultralow

jitter of 95fs

noise 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.
