Assuming that the FPGA has a clock multiplier to get much faster frequencies internally, what is good choice for an external crystal? Let's say I've got a Virtex 7 class FPGA, and I plan to run internally at ~150 MHz and have an external peripheral that needs at 283.0 MHz.

Most FPGA designs require stable clock signals, usually generated either from "crystals" or "oscillators". See Ecliptek , SaRonix and Vite as examples of quartz crystals and oscillators manufacturers.

Let’s highlight some key guidelines for selecting an optimal reference-clocking solution for your FPGA-based design. Flexibility FPGA-based applications can optimize their power and throughput by selecting an optimal reference-clock rate. The ability to quickly change the FPGA reference clock during the prototype and validation phases of

FPGA (Field-Programmable Gate Array) is a highly flexible integrated circuit with programmable logic and configurable internal connections. The unique feature of an FPGA is that it can be reprogrammed after manufacturing to perform different logical functions.

Nov 17, 2022 · Additionally, our study demonstrates that CRYSTALS-Kyber and Saber have very similar hardware performance. Both outperform NTRU in terms of execution time by a factor 36-62 for key generation and 3-7 for decapsulation, assuming the same security level.

May 3, 2022 · In general, being able to use an internal RC oscillator vs a dedicated crystal or oscillator is not a question of production quantity, but rather based on the specific application.

Aug 13, 2021 · "The crystal oscillator provides up to a 20 MHz clock signal. Physically, it requires connection to an external crystal, however, for simulation purposes the XTL pin provides a clock signal running at the desired input frequency."

Jun 15, 2021 · It then provides a step-by-step guide for selecting a crystal for FPGA designs, including considering clock frequency, stability requirements, crystal package size, power consumption, frequency tolerance, aging characteristics, availability, and cost.

Is it necessary to connect a clock crystal/ external clock source for Artix7 (or any) FPGA. If 'Yes', to which pins? I'm using XC7A35T-FTG256C. Thank you...

Mar 19, 2016 · I'm working on a project using an Altera MAX II FPGA. I need to output a relatively accurate (<1ppm) signal and clock @ 100Mhz (to a DAC). Is a 10Mhz 0.3ppm TXCO suitable, or should I go with a 25Mhz or 50Mhz crystal instead.
