This ADC family addresses the key requirements for maximizing performance of high sensitivity receivers and data acquisition systems. Exceptional SFDR performance of 100dBc, combined with SNR of up to 81.6dB, enable the ADCs to resolve low level signals in the presence of large interferers and blockers. The LTC2209 family uses innovative ADC technology for digital receivers by incorporating two unique features that simplify receiver design and improve system performance. The first is an internal transparent dither circuit that improves the ADCs spurious free dynamic range response well beyond 100dBc for low level input signals. The second feature is a digital output randomizer that dramatically reduces unwanted tones caused by digital feedback. All ADCs excluding LTC2215, LTC2216 and LTC2217 feature a programmable gain amplifier (PGA) front end that eases the ADC driver output power requirements when driving the lower input range of 1.5Vp-p for improved distortion performance. The LTC2274 series offers a high speed, 2-wire serial interface for interfacing to the SerDes port offered on most FPGAs.

Using this powerful software tool, engineers can evaluate the performance of Linear Technology’s high speed ADC and signal chain receiver family. For a simple program it performs complicated calculations in seconds. PScope software allows engineers to evaluate the signal-to-noise ratio (SNR), spurious free dynamic range (SFDR), total harmonic distortion (THD), as well as other key parameters of high speed ADCs quickly and easily. PScope can also perform more complicated calculations such as intermodulation distortion from a 2-tone test, or adjacent channel power ratios (ACPR) from a spread spectrum signal with the click of a button. It also supports multiple channel ADCs such as the LTM9011, allowing the measurement of eight ADC channels simultaneously.
