FAQ

What is the maximum transceiver data rate supported by XC6VLX240T-1FF1156C?

The XC6VLX240T-1FF1156C supports GTX transceivers with a maximum data rate of 15.4 Gb/s per lane. This rate is validated across process, voltage, and temperature corners for protocols including CPRI, SATA III, and SRIO. The XC6VLX240T-1FF1156C transceiver architecture uses a dedicated clocking path and analog equalization to maintain signal integrity at this line rate without external retiming.

Does XC6VLX240T-1FF1156C include a hard PCIe Gen2 endpoint?

Yes, the XC6VLX240T-1FF1156C integrates a hard PCIe Gen2 x8 endpoint compliant with the PCI Express Base Specification Revision 2.1. This block handles link training, transaction layer packet routing, and data link layer acknowledgments without consuming programmable logic resources. The XC6VLX240T-1FF1156C PCIe interface operates at 5 GT/s per lane with full error reporting and power management support.

What I/O standards are supported by XC6VLX240T-1FF1156C banks?

The XC6VLX240T-1FF1156C supports LVDS, BLVDS, RSDS, mini-LVDS, LVPECL, SSTL-18/25, HSTL-I/II, and TMDS across its 16 I/O banks. Each bank accepts independent VCCO voltages from 1.2 V to 3.3 V, enabling simultaneous operation of DDR3 memory interfaces at 1.5 V and video outputs at 3.3 V. The XC6VLX240T-1FF1156C I/O architecture includes programmable slew rate and drive strength controls per pin group.

How many block RAM bits does XC6VLX240T-1FF1156C provide?

The XC6VLX240T-1FF1156C contains 14,742 kbits of total block RAM, implemented as 36-kbit dual-port RAM primitives. These BRAMs support true dual-port read/write operations, byte-write enable, and parity generation. The XC6VLX240T-1FF1156C BRAM distribution allows up to 4096 independent 36-kbit instances or cascaded configurations for larger memory depths, essential for packet buffering and FFT twiddle storage.

What is the purpose of the VCCAUX supply on XC6VLX240T-1FF1156C?

VCCAUX supplies 1.8 V to the XC6VLX240T-1FF1156C configuration logic, clock management tiles (MMCM/PLL), and transceiver analog circuitry. It powers internal reference generators and bias networks critical for transceiver jitter performance and clock synthesis stability. The XC6VLX240T-1FF1156C requires VCCAUX to be ramped within specified sequencing tolerances relative to VCCINT to ensure reliable configuration and startup behavior.
