The input range of the ADC can be optimized with the PGA front end. The LTC2207-14/LTC2206-14 are perfect for demanding communications applications, with AC performance that includes 77.3dB SNR and 98dB spurious free dynamic range (SFDR). Ultralow jitter of 80fsRMS allows under- sampling of high input frequencies with excellent noise performance. Maximum DC specs include ±1.5LSB INL, ±1LSB DNL (no missing codes) over temperature. A separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V. 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 al- lows high performance at full speed with a wide range of clock duty cycles. n Telecommunications n Receivers n Cellular Base Stations n Spectrum Analysis n Imaging Systems n ATE n Sample Rate: 105Msps/80Msps n 77.3dBFS Noise Floor n 98dB SFDR n SFDR >82dB at 250MHz (1.5VP-P Input Range) n PGA Front End (2.25VP-P or 1.5VP-P Input Range) n 700MHz Full Power Bandwidth S/H n Optional Internal Dither n Optional Data Output Randomizer n Single 3.3V Supply n Power Dissipation: 947mW/762mW n Optional Clock Duty Cycle Stabilizer n Out-of-Range Indicator n Pin-Compatible Family 105Msps: LTC2207 (16-Bit), LTC2207-14 (14-Bit) 80Msps: LTC2206 (16-Bit), LTC2206-14 (14-Bit) 65Msps: LTC2205 (16-Bit), LTC2205-14 (14-Bit) 40Msps: LTC2204 (16-Bit) 25Msps: LTC2203 (16-Bit) Single-Ended Clock 10Msps: LTC2202 (16-Bit) Single-Ended Clock n 48-Pin 7mm × 7mm QFN Package – + S/H AMP CORRECTION LOGIC AND SHIFT REGISTER OUTPUT DRIVERS 14-BIT PIPELINED ADC CORE INTERNAL ADC REFERENCE GENERATOR 1.25V COMMON MODE BIAS VOLTAGE CLOCK/DUTY CYCLE CONTROL D13 • • • D0 ENC+ PGA SHDN DITH MODE OE RAND ENC– VCM ANALOG INPUT 2207614 TA01 0.5V TO 3.6V 3.3V 3.3V SENSE OGND OVDD 2.2μF 0.1μF 0.1μF 0.1μF 0.1μF VDD GND ADC CONTROL INPUTS AIN+ AIN– OF CLKOUT+ CLKOUT– LTC2207-14: 32K Point FFT, fIN = 14.86MHz, –1dBFS, PGA = 0, 105Msps L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
