FAQ

What is the maximum supported transceiver data rate for XC6VLX240T-L1FFG1156C?

The XC6VLX240T-L1FFG1156C supports transceiver data rates from 600 Mb/s up to 11.18 Gb/s per lane. This range enables compliance with PCIe Gen2, SATA II/III, SRIO 2.1, and OTU3/OTU4 protocols. Operation at 11.18 Gb/s requires proper board-level signal integrity design, including controlled impedance routing and appropriate termination. The XC6VLX240T-L1FFG1156C transceiver architecture uses a dedicated clocking structure with integrated CDR and elastic buffers to maintain jitter tolerance within specification.

Does XC6VLX240T-L1FFG1156C support JTAG boundary-scan testing?

Yes, XC6VLX240T-L1FFG1156C fully supports IEEE 1149.1 JTAG boundary-scan testing via dedicated TDI, TDO, TCK, and TMS pins. The device implements a 4-bit instruction register and supports SAMPLE/PRELOAD, EXTEST, INTEST, and BYPASS instructions. JTAG is used for both configuration and post-configuration verification, including I/O pin state capture and interconnect testing. The XC6VLX240T-L1FFG1156C also allows concurrent JTAG access while the FPGA is operating in user mode.

What configuration modes are supported by XC6VLX240T-L1FFG1156C?

XC6VLX240T-L1FFG1156C supports Master SPI, Slave Serial, Slave SelectMAP, and JTAG configuration modes. Master SPI uses an internal oscillator to drive external SPI flash; Slave Serial accepts configuration data from a microcontroller over a single bidirectional line; Slave SelectMAP enables high-speed parallel loading via 8-, 16-, or 32-bit bus; JTAG allows programming and debugging through standard boundary-scan infrastructure. All modes support AES-encrypted bitstreams, and the XC6VLX240T-L1FFG1156C validates decryption keys before releasing configuration data to the fabric.

Is XC6VLX240T-L1FFG1156C qualified for automotive applications?

No, XC6VLX240T-L1FFG1156C is rated for industrial temperature range (–40°C to +100°C junction) and is not AEC-Q100 qualified. It lacks automotive-specific reliability testing, failure-in-time (FIT) reporting, and extended temperature screening required for automotive ECUs or ADAS systems. For automotive use cases, AMD recommends evaluating the XA series derivatives or newer Versal ACAP automotive-grade variants. The XC6VLX240T-L1FFG1156C remains suitable for industrial control, telecom infrastructure, and test equipment where industrial qualification suffices.

How many clock management tiles (CMTs) does XC6VLX240T-L1FFG1156C contain?

XC6VLX240T-L1FFG1156C contains 24 clock management tiles (CMTs), each integrating two Digital Clock Managers (DCMs) and one Phase-Locked Loop (PLL). These CMTs provide independent clock synthesis, phase shifting, duty-cycle correction, and frequency multiplication/division. They support up to 24 simultaneous clock domains with jitter filtering capabilities. The XC6VLX240T-L1FFG1156C leverages CMTs to generate precise clock signals for transceivers, memory interfaces, and logic domains without external clock generators.
