The Texas Instruments ADS54J64 quad-channel, 14-bit, 1GSPS, analog-to-digital converter offers wide-bandwidth, 2x oversampling and high SNR. The device supports a JESD204B serial interface with data rates up to 10Gbps with one lane per channel. The buffered analog input provides uniform impedance across a wide frequency range and minimizes sample-and-hold glitch energy. The device provides excellent spurious-free dynamic range over a large input frequency range with very low power consumption. The digital signal processing block includes complex mixers followed by low-pass filters with decimate-by-two and four options supporting up to a 200MHz receive bandwidth. The ADS54J64 also supports a 14-bit, 500MSPS output in DDC bypass mode. A four-lane JESD204B interface simplifies connectivity, allowing high system integration density. An internal phase-locked loop multiplies the incoming ADC sampling clock to derive the bit clock that is used to serialize the 14-bit data from each channel.
