Product Summary
The LTC2220IUP#PBF is an Analog Digital Converter. The LTC2220IUP#PBF is a 185Msps, sampling 12-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2220IUP#PBF is perfect for demanding communications applications with AC performance that includes 67.5dB SNR and 80dB spurious free dynamic range for signals up to 170MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance. DC specs include ±0.7LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.5LSBRMS. 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 3.6V. The applications of the LTC2220IUP#PBF include Wireless and Wired Broadband Communication, Cable Head-End Systems, Power Amplifier Linearization and Communications Test Equipment.
