Quad-Channel, 14-Bit, 1-GSPS, 2x-Oversampling Analog-to-Digital Converter (ADC)

 

Description

The ADS54J64 device is a quad-channel, 14-bit,
1-GSPS, analog-to-digital converter (ADC) offering wide-bandwidth, 2x oversampling and high SNR. The ADS54J64 supports a JESD204B serial interface with data rates up to 10 Gbps 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 ADS54J64 provides excellent spurious-free dynamic range (SFDR) 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-2 and -4 options supporting up to a 200-MHz receive bandwidth. The ADS54J64 also supports a 14-bit, 500-MSPS output in DDC bypass mode.

A four-lane JESD204B interface simplifies connectivity, allowing high system integration density. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock that is used to serialize the 14-bit data from each channel.
