ChannelCore Flex is a
major breakthrough. It can be configured to support many thousands of channels, spanning an input bandwidth exceeding 1 GHz. Importantly, these channels can have individual bandwidths that can vary by several orders of magnitude, be overlapped to accommodate broadband transmissions, and have centre frequencies and sample rates that can be independently tuneable to sub-Hertz resolution (≤1Hz). The end result is a Channelizer architecture that can be configured to support concurrent monitoring of multiple channels, with bandwidths ranging from as large as hundreds of Megahertz, to as narrow as a few Hertz, delivering an overall aggregate channelized sample rate that can exceed 1GS/s.
Application areas include Electronic Surveillance, satellite communications, flexible Base Station architectures and many others...

Implementation
There is no optimal, ‘one size fits all,’ Channelizer architecture, as each application places very different demands on the implementation. RFEL has resolved this problem by producing an IP core that is compile and run-time programmable from a simple set of parameters derived from the user’s technical specification. The end result is a high-performance and optimized IP core that has precisely the required level of flexibility demanded by the application, while minimising hardware cost and delivering a fast time-to-market.
ChannelCore Flex is available for licensing, targeted to a wide range of Xilinx or Altera FPGA devices.
Key Features
-
Can process two complex inputs, with an aggregate input sample rate of 500 MS/s in mid-range FPGAs and potentially >1GS/s for certain channel plans in high-end devices.
-
Fits within a single FPGA, e.g. the Xilinx Spartan 6, V4 to V7, or the Altera Stratix.
-
Can support several thousand independently defined channels.
-
Each channel can have a user-defined gain (90 dB range), filter response, centre frequency, bandwidth and sample rate (all accurate to 0.06 Hz).
-
Any of the channels can be reprogrammed at run-time, without interrupting the operation of other channels.
-
Can support a range of input formats and sample rates.
-
Global frequency offsets can be independently applied to the inputs.
-
A spurious free dynamic range (SFDR) exceeding 80 dB, and an alias-free bandwidth of 80% of the output sample rate, can be easily achieved with a 0.1 dB peak-to-peak pass-band ripple.
-
Can be tailored to minimise the required FPGA resources for a specified performance.
