    Demo Board for LTC2188 - 16-Bit, 20Msps Low Power Dual ADC

    Overview

    Demonstration circuit 1620A supports the LTC2185/LTC2145 family DDR LVDS output mode. Depending on the required resolution and sample rate, the DC1620A is supplied with the appropriate ADC. The circuitry on the analog inputs is optimized for analog input frequencies from 5MHz to 70MHz. Refer to the data sheet for proper input networks for different input frequencies.

    The LTC®2188 is a two-channel simultaneous sampling 16-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 77dB SNR and 90dB spurious free dynamic range (SFDR). Ultralow jitter of 0.07psRMS allows undersampling of IF frequencies with excellent noise performance.
