3 Description

The ADC12DJ5200SE is an RF-sampling, gigasample,

analog-to-digital converter (ADC) with

integrated input baluns. The ADC12DJ5200SE can

be configured as a dual-channel, 5.2 GSPS ADC or

single-channel, 10.4 GSPS ADC. The -3 dB input

frequency range of 2 to 6.3 GHz enables direct RF

sampling of S-band and C-band for frequency agile

systems.

The ADC12DJ5200SE uses a high-speed JESD204C

output interface with up to 16 serialized lanes

supporting up to 17.16 Gbps line rate. Deterministic

latency and multi-device synchronization is supported

through JESD204C subclass-1. The JESD204C

interface can be configured to trade-off line rate and

number of lanes. Both 8b/10b and 64b/66b data

encoding schemes are supported. 64b/66b encoding

supports forward error correction (FEC) for improved

bit error rates. The interface is backwards compatible

with JESD204B receivers.

Innovative synchronization features, including

noiseless aperture delay adjustment and SYSREF

windowing, simplify system design for multi-channel

applications. Optional digital down converters (DDCs)

are available to provide digital conversion to

baseband and to reduce the interface rate. A

programmable FIR filter allows on-chip equalization.
