The ADS54J42 is a low-power, wide-bandwidth, 14-bit, 625-MSPS, dual-channel, analog-to-digital converter (ADC). Designed for high signal-to-noise ratio (SNR), the device delivers a noise floor of –157 dBFS/Hz for applications aiming for highest dynamic range over a wide instantaneous bandwidth. The device supports the JESD204B serial interface with data rates up to 6.25 Gbps. The buffered analog input provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy. Each ADC channel optionally can be connected to a wideband digital down-converter (DDC) block. The ADS54J42 provides excellent spurious-free dynamic range (SFDR) over a large input frequency range with very low power consumption.

The JESD204B interface reduces the number of interface lines, allowing high system integration density. An internal phase-locked loop (PLL) multiplies the ADC sampling clock to derive the bit clock that is used to serialize the 14-bit data from each channel.
