ADC32RF45IRMP

The ADC32RF45IRMP is a dual-channel, 14-bit, 3 GSPS analog-to-digital converter from Texas Instruments designed for RF-sampling applications. With a 3200 MHz analog input bandwidth, it supports direct sampling of signals up to 4 GHz. The device uses a pipeline architecture and provides a JESD204B interface with subclass 1 deterministic latency, supporting up to 4 lanes per channel at 12.5 Gbps.

Typical performance includes 63 dB SNR, 10 ENOB, and 77 dB SFDR. The ADC achieves 60.9 dBFS SNR and 77 dBc worst spur SFDR at 900 MHz, and 58.8 dBFS SNR with 75 dBc worst spur SFDR at 1.78 GHz. Channel isolation is 95 dB at 1.8 GHz, and the aperture jitter is 90 fs. The noise floor is -155 dBFS/Hz. Power consumption is 6400 mW typical for both channels, with 3.2 W per channel at 3 GSPS.

The ADC includes on-chip features such as an input buffer, internal reference, input clamp for overvoltage protection, programmable power detectors, dither, and input termination. It also supports up to four digital down-converters (DDCs) with independent NCOs. The device is available in a 72-VQFN (10x10 mm) surface-mount package with exposed pad. Operating temperature range is -40°C to 85°C.
