The LTC2242-12 is a 250Msps, sampling 12-bit A/D converter 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 95fsRMSallows IF undersampling with excellent 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+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.BitsLTC2242-1010LTC2242-1212ApplicationsWireless and Wired Broadband CommunicationCable Head-End SystemsPower Amplifier LinearizationCommunications Test Equipment
