250MHz, 12-bit High Speed Delta Sigma ADC for 5G, LiDAR and Imaging

Overview

The SM-CTDSM-250M is a 12-bit continuous-time delta-sigma (CT??) analog-to-digital converter IP. By leveraging Seamless’ patented Switched-Mode Signal Processing (SMSP) technology, our ADC seamlessly fits into system-on-chip integrated circuits requiring only small area and low power. With up to 250MHz input signal bandwidth, 60dB of SNDR, high clock jitter tolerance and a resistive input, SM-CTDSM-250M’s over-sampling architecture is extremely well suited for high-speed transceivers and LiDAR applications.
