FAQ

What is the maximum operating frequency supported by the XC4VLX100-10FFG1148C?

The XC4VLX100-10FFG1148C carries the -10 speed grade, indicating guaranteed timing performance up to 500 MHz for internal logic paths under worst-case commercial conditions. Critical paths involving DCM outputs or I/O registers may achieve >600 MHz depending on placement and routing. The actual achievable system clock depends on design constraints and synthesis results, not a fixed upper limit.

Does the XC4VLX100-10FFG1148C support partial reconfiguration?

Yes, the XC4VLX100-10FFG1148C supports partial reconfiguration through Xilinx ISE design tools and the ICAP (Internal Configuration Access Port). This allows dynamic swapping of logic modules without resetting the entire device, enabling runtime adaptation in applications like protocol gateways and adaptive test systems where continuous operation is critical.

What I/O standards are supported by the XC4VLX100-10FFG1148C?

The XC4VLX100-10FFG1148C supports 18 SelectIO standards including LVCMOS, LVTTL, SSTL-2 Class I/II, HSTL-I/III, LVDS, and BLVDS. Each I/O bank is independently configurable for voltage (1.2 V to 3.3 V) and standard, enabling mixed-voltage board designs and interoperability with legacy and modern peripherals.

How many Digital Clock Managers (DCMs) does the XC4VLX100-10FFG1148C include?

The XC4VLX100-10FFG1148C integrates eight Digital Clock Managers (DCMs), each capable of frequency synthesis (×2 to ×32), phase shifting (0°–360° in 1/256 steps), and duty-cycle correction. These DCMs operate independently and can drive multiple clock networks, supporting complex multi-clock domain architectures in the XC4VLX100-10FFG1148C.

Is the XC4VLX100-10FFG1148C still in active production?

The XC4VLX100-10FFG1148C is a mature Virtex-4 device no longer in active production by AMD/Xilinx, but Aetrix Electronics maintains verified inventory and long-term supply agreements for continued support in legacy industrial, aerospace, and medical programs requiring obsolescence mitigation.
