FAQ
What is the maximum supported transceiver data rate for XC4VSX35-11FF668C?
The XC4VSX35-11FF668C supports RocketIO GTP transceivers rated up to 2.5 Gbps per lane. This specification is guaranteed across commercial temperature range (0°C to 85°C) and applies to all 16 transceiver channels. The XC4VSX35-11FF668C does not support rates beyond 2.5 Gbps-even with external equalization or forward error correction enabled.
Does XC4VSX35-11FF668C include embedded processors?
Yes, the XC4VSX35-11FF668C integrates two hard-core PowerPC 405 processors with 32 kB instruction and 32 kB data caches each. These are fully functional, JTAG-debuggable CPUs that execute code from on-chip or external memory. The XC4VSX35-11FF668C's processor subsystem includes PLB bus interface and integrated interrupt controller.
What I/O standards are supported by XC4VSX35-11FF668C?
The XC4VSX35-11FF668C supports LVCMOS, LVTTL, HSTL, SSTL, and differential LVDS across its 352 I/O pins. Each I/O bank is independently configurable for voltage (1.2 V to 3.3 V), drive strength, and on-die termination. The XC4VSX35-11FF668C does not support PCI-X or HyperTransport signaling natively.
What is the logic capacity of XC4VSX35-11FF668C in terms of equivalent ASIC gates?
The XC4VSX35-11FF668C contains 34,560 logic cells, which Xilinx documentation equates to approximately 120,000 ASIC gates. This metric reflects combinational logic capability excluding memory or DSP resources. The XC4VSX35-11FF668C's actual usable gate count depends on placement density, routing congestion, and utilization of block RAM or DSP48 slices.
Is XC4VSX35-11FF668C still in active production?
No-XC4VSX35-11FF668C was discontinued by AMD (formerly Xilinx) in 2011. Aetrix Electronics maintains legacy inventory and offers extended lifecycle support, including obsolescence mitigation, cross-reference assistance, and traceable sourcing for the XC4VSX35-11FF668C.
