3 Description
The ADC32RF44 device is a 14-bit, 2.6-GSPS, dual-
channel,
analog-to-digital
converter
(ADC)
that
supports RF sampling with input frequencies up to
4 GHz and beyond. Designed for high signal-to-noise
ratio (SNR), the ADC32RF44 delivers a noise
spectral density of –154.2 dBFS/Hz as well as
dynamic range and channel isolation over a large
input frequency range. The buffered analog input with
on-chip termination provides uniform input impedance
across a wide frequency range and minimizes
sample-and-hold glitch energy.
Each ADC channel can be connected to a dual-band,
digital
down-converter
(DDC)
with
up
to
three
independent, 16-bit numerically-controlled oscillators
(NCOs) per DDC for phase-coherent frequency
hopping. Additionally, the ADC is equipped with front-
end peak and RMS power detectors and alarm
functions to support external automatic gain control
(AGC) algorithms.
The ADC32RF44 supports the JESD204B serial
interface with subclass 1-based deterministic latency
using data rates up to 12.5 Gbps with up to four lanes
per ADC. The device is offered in a 72-pin VQFN
package (10 mm × 10 mm) and supports the
industrial temperature range (–40°C to +85°C).
