48-Lead (7mm × 7mm) QFN Package The LTC®2123 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 …
