1. General description
The ADC1443D is a dual channel 14-bit Analog-to-Digital Converter (ADC) with
JESD204B interface (which is backward compatible with the JESD204A interface)
optimized for high dynamic performance and low power consumption at sample rates up
to 185 Msps. Pipelined architecture and output error correction guarantee zero missing
codes over the entire operating range.
Supplied from a single 1.8 V source, the ADC1443D has JESD204B serial outputs over a
configurable number of lanes (1 or 2). Multiple Device Synchronization (MDS) allows
sample-accurate synchronization of the data outputs of multiple ADC devices. It
guarantees a maximum skew of one clock period between as many as 16 output lanes
from up to eight ADC1443D devices.
An integrated Serial Peripheral Interface (SPI) allows easy configuration of the ADC. The
device also includes a programmable full-scale to allow a flexible input voltage range of
1 V (p-p) to 2 V (p-p).
With an analog banwidth from the baseband to input frequencies of up to 1 GHz (typical),
the ADC1443D is ideal for use in undersampled multi-carrier, multistandard
communication system applications.
