Description

The ADC12DJ5200RF device is an RF-sampling, giga-sample, analog-to-digital converter (ADC) that can directly sample input frequencies from DC to above 10 GHz. ADC12DJ5200RF can be configured as a dual-channel, 5.2 GSPS ADC or single-channel, 10.4 GSPS ADC. These operating modes allow programmable tradeoffs in channel count and Nyquist bandwidth allows for flexible hardware that meets the needs of multiple applications. Useable input frequency range of up to 10 GHz enables direct RF sampling of L-band, S-band, C-band, and X-band for frequency agile systems.

The ADC12DJ5200RF 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 when using 8B/10B encoding modes.

Innovative synchronization features, including noiseless aperture delay (TAD) 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.
