The LTC2123 is a 2-channel simultaneous sampling 250Msps 14-bit A/D converter with serial JESD204B outputs. It is designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding communications applications with AC performance that includes 70dBFS SNR and 90dBFS spurious free dynamic range (SFDR). The 1.25GHz input bandwidth allows the ADC to under-sample high frequencies.
The 5Gbps JESD204B serial interface simplifies the PCB design by minimizing the number of data lines required.
The DEVCLK+ and DEVCLK– inputs can be driven differentially with sine wave, PECL, or LVDS signals. An optional clock divide-by-two circuit or clock duty cycle stabilizer maintains high performance at full speed for a wide range of clock duty cycles.
