NOTICE OF INTENT RFSoC Integrated Microwave Readout Electronics

Requirements / Specifications Document TITLE: RFSoC Integrated Microwave Readout Electronics PR NUMBER: NB687000-26-02197 Requesting Laboratory / Division / Group: Physical Measurements Laboratory / Applied Physics Division / Quantum Microcalorimeter Group GENERAL STATEMENT OF NEED: The Quantum Microcalorimeter Group requires a Radio Frequency System-on-Chip (RFSoC) Integrated Microwave Readout Electronics. The purpose of these electronics will be for the readout and operation of large arrays of x-ray detectors under development at NIST. The electronics must be able to generate, convert to analog, receive and digitize, and process hundreds of sinusoidal tones at frequencies ranging from 1 MHz to 1 GHz. In order to leverage and be compatible with previous NIST work, these electronics must be based on the Xilinx Zynq UltraScale+ RFSoC (Radio Frequency System on Chip). We require an integrated development platform of electronics compatible with a PCI-express interfaces of a PC (Personal Computer) and based on a 3rd Generation (or newer when available) Xilinx RFSoC chip. BACKGROUND: NIST develops detector arrays with channel counts in the thousands of detectors. In order to operate and read out data from the detector, each must be electrically interrogated with a unique sinusoidal tone with a frequency at the channel’s unique resonant frequency. Specialized electronics are needed in order to simultaneously generate and read hundreds, and up to thousands, of these unique sinusoidal tones. NIST develops its own firmware and software for operating these electronics. OBJECTIVE: The electronics must be capable of generating hundreds of frequency tones, convert to analog, receive and digitize returning tones, provide filtering and decimation, and communications to stream results. Each tone must be dynamically programmable based on the needs of the particular detectors. The base frequencies required range from 1 MHz to 1 GHz, which may be upconverted to higher frequencies using separate intermediate frequency (IF) electronics not included or required in this acquisition. NIST has developed its own firmware and software that will be used to operate the electronics.
