10G/40G Ethernet / PCI Express Reference Design


HTG-K816: Xilinx Kintex UltraScale™ Half Size PCI Express Development Platform
Datacenter Customizable Platform

Base board + X2QSFP+ Daughter card

Populated with Xilinx Kintex UltraScale™  040 or 060 FPGA , the HTG-K816 network card provides access to eight  lanes of PCI Express Gen 3 ( 8 x 8Gbps),  two independent banks of DDR4 (72-bit) memory components (5GB), and front panel Z-Ray interface for hosting high-speed mezzanine cards.  The Z-RAY port is  populated with up to 16 GTH (16x16.3G) serial transceivers along with power (12V/5A, 3.3V/16A, & VCCIO/1A), differential clocks, and control signals (single-ended and I2C I/Os).  The Z-Ray interface allows quick customization of the platform to host different communication and processing ports for different applications. HiTech Global offers Z-RAY mezzanine modules with Hybrid Memory Cube (HMC),  QSFP+, SFP+, FireFly , CXP, etc. HiTech Global also offers design services for any custom Z-RAY module requiring access to the GTH serial transceivers of the onboard Kintex UltraScale FPGA.

The HTG-K816 is also available for high volume production.
