Product Specification
General Description
Virtex®-6 CXT FPGAs provide designers needing power-optimized 3.75 Gb/s transceiver performance with an optimized
ratio of built-in system-level blocks. These include 36 Kb block RAM/FIFOs, up to 15 Mb of block RAM, up to 768 DSP48E1
slices, enhanced mixed-mode clock management blocks, PCI Express® (GEN 1) compatible integrated blocks, a tri-mode
Ethernet media access controller (MAC), up to 241K logic cells, and strong IP support. Using the third generation ASMBL™
(Advanced Silicon Modular Block) column-based architecture, the Virtex-6 CXT family also contains SelectIO™ technology
with built-in digitally controlled impedance, ChipSync™ source-synchronous interface blocks, enhanced mixed-mode clock
management blocks, and advanced configuration options. Customers needing higher transceiver speeds, greater I/O
performance, additional Ethernet MACs, or greater capacity should instead use the Virtex-6 LXT or SXT families. Built on a
40 nm state-of-the-art copper process technology, Virtex-6 CXT FPGAs are a programmable alternative to custom ASIC
technology. Virtex-6 CXT FPGAs are the programmable silicon foundation for Targeted Design Platforms that deliver
integrated software and hardware components to enable designers to focus on innovation as soon as their development
cycle begins.

GTX Transceivers in CXT Devices
CXT devices have between 8 to 16 gigabit transceiver circuits. Each GTX transceiver is a combined transmitter and receiver
capable of operating at a data rate between 480 Mb/s and 3.75 Gb/s. Lower data rates can be achieved using FPGA logic-
based oversampling. The transmitter and receiver are independent circuits that use separate PLLs to multiply the reference
frequency input by certain programmable numbers between 2 and 25, to become the bit-serial data clock. Each GTX
transceiver has a large number of user-definable features and parameters. All of these can be defined during device
configuration, and many can also be modified during operation.
