3 Description  
The ADC31JB68 is a low power, wide bandwidth 16-  
bit 500 MSPS analog-to-digital converter (ADC). The  
buffered analog input provides uniform input  
impedance across a wide frequency range while  
minimizing sample-and-hold glitch energy. It is  
designed to sample input signals of up to 1.3 GHz.  
Input Amplitude and Phase Adjustment  
Input Full Scale: 1.7 Vpp  
Power Supplies: 1.2/1.8/3 V  
JESD204B Interface  
Subclass 1 Compliant  
2 Lanes at 5 Gbps  
The ADC31JB68 provides excellent spurious-free  
dynamic range (SFDR) over a large input frequency  
range with very low power consumption. On-chip  
dither provides an very clean noise floor. Embedded  
foreground and background calibration ensures  
consistent performance over the temperature range  
and minimizes part to part variation.  
Support for Multi-chip Synchronization  
Key Specifications  
Power Dissipation: 915 mW at 500 Msps  
Performance at fin = 210 MHz at –1 dBFS  
SNR: 69.3 dBFS  
It supports the JESD204B serial interface with data  
rates up to 5 Gbps on each of 2 lanes, enabling high  
system integration density.  
NSD: –153.3 dBFS/Hz  
SFDR: 80 dBc  
Non-HD2,HD3: –91 dBFS  
The device comes in a 40-pin QFN (6 x 6 mm)  
package.  
Performance at fin = 450 MHz at –1 dBFS  
SNR: 67 dBFS
