LTC2209 16-Bit, 160Msps ADC Features Description n Sample Rate: 160Msps The LTC 2209 is a 160Msps 16-bit A/D converter designed n 77.3dBFS Noise Floor for digitizing high frequency, wide dynamic range signals n 100dB SFDR with input frequencies up to 700MHz. The input range of n SFDR >84dB at 250MHz (1.5V Input Range) the ADC can be optimized with the PGA front end. P-P n PGA Front End (2.25V or 1.5V Input Range) P-P P-P The LTC2209 is perfect for demanding communications n 700MHz Full Power Bandwidth S/H applications, with AC performance that includes 77.3dBFS n Optional Internal Dither Noise Floor and 100dB spurious free dynamic range n Optional Data Output Randomizer (SFDR). Ultra low jitter of 70fs allows undersampling RMS n LVDS or CMOS Outputs of high input frequencies with excellent noise performance. n Single 3.3V Supply Maximum DC specs include 5.5LSB INL, 1LSB DNL (no n Power Dissipation: 1.53W missing codes). n Clock Duty Cycle Stabilizer n The digital output can be either differential LVDS or Pin-Compatible Family: single-ended CMOS. There are two format options for 130Msps: LTC2208 (16-Bit), LTC2208-14 (14-Bit) the CMOS outputs: a single bus running at the full data 105Msps: LTC2217 (16-Bit) n rate or demultiplexed busses running at half data rate. A 64-Pin (9mm 9mm) QFN Package separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V. a + The ENC and ENC inputs may be driven differentially n Telecommunications or single-ended with a sine wave, PECL, LVDS, TTL or n Receivers CMOS inputs.
