FeaTures DescripTion
n 77dB SNR The LTC®2162/LTC2161/LTC2160 are sampling 16-bit A/D n 90dB SFDR converters designed for digitizing high frequency, wide n Low Power: 87mW/63mW/45mW dynamic range signals. They are perfect for demanding n Single 1.8V Supply communications applications with AC performance that n CMOS, DDR CMOS, or DDR LVDS Outputs includes 77dB SNR and 90dB spurious free dynamic range n Selectable Input Ranges: 1VP-P to 2VP-P (SFDR). Ultralow jitter of 0.07psRMS al ows undersampling n 550MHz Full Power Bandwidth S/H of IF frequencies with excellent noise performance. n Optional Data Output Randomizer DC specs include ±2LSB INL (typ), ±0.5LSB DNL (typ) n Optional Clock Duty Cycle Stabilizer and no missing codes over temperature. The transition n Shutdown and Nap Modes noise is 3.3LSBRMS. n Serial SPI Port for Configuration n 48-Pin (7mm × 7mm) QFN Package The digital outputs can be either full rate CMOS, double data rate CMOS, or double data rate LVDS. A separate output power supply allows the CMOS output swing to
