FAQ

What is the maximum supported transceiver data rate for XC5VSX50T-1FFG665CES?

The XC5VSX50T-1FFG665CES integrates RocketIO GTP transceivers rated for operation from 600 Mb/s up to 3.75 Gb/s. This rate is guaranteed under industrial temperature conditions (-40°C to +100°C) and with proper PCB layout, power delivery, and reference clock jitter below 100 ps RMS. The XC5VSX50T-1FFG665CES does not support rates beyond 3.75 Gb/s, even with external equalization.

Does XC5VSX50T-1FFG665CES support JTAG boundary-scan testing?

Yes, XC5VSX50T-1FFG665CES fully supports IEEE 1149.1 JTAG boundary-scan testing through dedicated TCK, TMS, TDI, and TDO pins. The device implements mandatory instructions (SAMPLE/PRELOAD, EXTEST, BYPASS) and optional IDCODE, and supports configuration via JTAG using iMPACT or Vivado tools. Boundary-scan capability is active during all operational states except during active configuration loading.

What configuration modes are supported by XC5VSX50T-1FFG665CES?

XC5VSX50T-1FFG665CES supports five configuration modes selected via M0–M2 pins: Master SelectMAP, Slave SelectMAP, Slave Serial, JTAG, and System ACE. Each mode defines how configuration data is loaded-either from external flash (Master/Slave SelectMAP), serial PROM (Slave Serial), host processor (System ACE), or debugger (JTAG). Mode selection is latched at power-up and cannot be changed dynamically.

Is XC5VSX50T-1FFG665CES qualified for aerospace applications?

XC5VSX50T-1FFG665CES is not a radiation-hardened or QML-V qualified part, but it is screened and tested to meet extended industrial temperature range (-40°C to +100°C) and operates reliably in non-radiation environments such as aircraft avionics and ground-based radar systems. For spaceflight use, additional screening, burn-in, and radiation testing would be required beyond standard XC5VSX50T-1FFG665CES specifications.

What is the purpose of the VCCAUX_IO supply in XC5VSX50T-1FFG665CES?

VCCAUX_IO supplies 2.5 V to internal I/O logic circuits-including input receivers, output drivers, and SelectIO calibration circuitry-in XC5VSX50T-1FFG665CES. It must be regulated within ±3% tolerance and decoupled with low-ESR capacitors near the package. Unlike VCCO, VCCAUX_IO is not user-configurable and remains active whenever the device is powered, enabling reliable I/O initialization prior to configuration completion.
