LTC2240-10 10-Bit, 170Msps ADC
FEATURES DESCRIPTION
n
Sample Rate: 170Msps
The LTC®2240-10 is a 170Msps, sampling 10-bit A/D con- n
60.6dB SNR
verter designed for digitizing high frequency, wide dynamic n
80dB SFDR
range signals. The LTC2240-10 is perfect for demanding n
1.2GHz Full Power Bandwidth S/H
communications applications with AC performance that n
Single 2.5V Supply
includes 60.6dB SNR and 80dB SFDR. Ultralow jitter of n
Low Power Dissipation: 445mW
95fsRMS allows IF undersampling with excellent noise n LVDS, CMOS, or Demultiplexed CMOS Outputs performance. n Selectable Input Ranges: ±0.5V or ±1V DC specs include ±0.3LSB INL (typ), ±0.1LSB DNL (typ) n No Missing Codes and no missing codes over temperature. n Optional Clock Duty Cycle Stabilizer n Shutdown and Nap Modes The digital outputs can be either differential LVDS, or n Data Ready Output Clock single-ended CMOS. There are three format options for n Pin Compatible Family the CMOS outputs: a single bus running at the full data 250Msps: LTC2242-12 (12-Bit), LTC2242-10 (10-Bit) rate or two demultiplexed buses running at half data rate 210Msps: LTC2241-12 (12-Bit), LTC2241-10 (10-Bit) with either interleaved or simultaneous update. A separate 170Msps: LTC2240-12 (12-Bit), LTC2240-10 (10-Bit) output power supply allows the CMOS output swing to 185Msps: LTC2220-1 (12-Bit)* range from 0.5V to 2.625V. 170Msps: LTC2220 (12-Bit), LTC2230 (10-Bit)* The ENC+ and ENC– inputs may be driven differentially or 135Msps: LTC2221 (12-Bit), LTC2231 (10-Bit)* single ended with a sine wave, PECL, LVDS, TTL, or CMOS n 64-Pin 9mm × 9mm QFN Package inputs. An optional clock duty cycle stabilizer allows high performance over a wide range of clock duty cycles.
