FAQ
What is the maximum data rate supported by the transceivers in XC5VSX35T-2FFG665C?
The XC5VSX35T-2FFG665C integrates RocketIO GTP transceivers rated for 1.0–2.5 Gbps operation. This supports PCIe Gen1 (2.5 GT/s), Serial RapidIO, and other protocols requiring sub-3 Gbps serial links. Each transceiver includes built-in 8B/10B encoding and elastic buffers to manage channel jitter.
Does XC5VSX35T-2FFG665C support configuration via SPI flash memory?
No, XC5VSX35T-2FFG665C does not natively support direct SPI flash configuration. It requires external microcontroller or PROM controller to implement Master SelectMAP or JTAG configuration. Xilinx recommends using Platform Flash XL or third-party controllers for SPI-based boot solutions.
What is the purpose of the M0–M2 pins on XC5VSX35T-2FFG665C?
The M0–M2 pins on XC5VSX35T-2FFG665C are mode selection inputs sampled at power-up to determine the configuration method. Valid combinations select JTAG, Slave Serial, or Master SelectMAP modes. These pins must be pulled high or low with appropriate resistors before configuration begins.
Can XC5VSX35T-2FFG665C operate in industrial temperature range?
No, XC5VSX35T-2FFG665C is specified only for commercial temperature range (0°C to +85°C). For extended temperature operation, engineers should consider the -1 speed grade variant with industrial qualification or evaluate newer AMD Versal devices with broader thermal ratings.
How many DSP48E slices are available in XC5VSX35T-2FFG665C?
The XC5VSX35T-2FFG665C contains 64 DSP48E slices. Each slice provides a 25×18 signed multiplier, wide accumulator, pipeline registers, and optional pre-adder functionality - enabling efficient FIR filter implementation, FFT butterfly operations, and real-time arithmetic-intensive algorithms.
