MezzanineBoard

2008-2009 Telemetry / Telecom series catalog - 7102 SRXL

Signal receiver and processor for L-band and IF

Description

e SRXL is a mezzanine board that pairs with an EDT main board (for PCI or PCI Express) to accept simulta- neous RF inputs in the L-band range of 925 to 2175 MHz and the IF range of 65 to 225 MHz. Each input is processed with a tun- able quadrature down-converter. e resulting baseband I and Q signals are low-pass filtered and digitized with 12- bit precision at programmable sample rates up to 65 MHz. e resulting four channels of digital sample data are available as inputs to the Xilinx Spartan 3 FPGA, which is programmable to perform signal processing or to serve as a configurable switch matrix to route data to the main board and up to two 4-channel digital down-converter Graychips (GC4016). e main board supplies high-speed DMA, plus additional memory and programmable FPGA resources.
