PCI Express SMA Evaluation Kit
General Description:
The DS50PCI401EVK – PCI Express (PCIe) SMA evaluation kit provides a complete high bandwidth
platform to evaluate the signal integrity and signal conditioning features of the National Semiconductor
DS50PCI401 – Quad Lane PCI Express transceiver with Equalization and De-emphasis.
SMA edge launch connectors are used as the input and the output connections for this evaluation
board. Commercially available adaptor boards can be purchased to facilitate connection to PCIe
cables or backplane interconnects.
Features:
• Quad lane bi-directional transceiver up to 5.0 Gbps rate
• Signal conditioning on inputs and outputs for extended reach
• Adjustable receive equalization up to +26 dB gain
• Adjustable transmit de-emphasis up to −12 dB
• Adjustable transmit VOD (600 mVp-p to 1200 mVp-p)
• <0.15 UI of residual DJ at 5.0 Gbps with 40” FR4 trace
• Automatic de-emphasis scaling based on rate detect
• PCIe: Beacon signal pass-through,
• Adjustable electrical IDLE detect threshold
• Low power (100 mW/channel), per-channel power down
• Programmable via pin selection or SMBus interface
• Single supply operation at 2.5V ±5%
• >6 kV HBM ESD Rating
• 3.3V LVCMOS input tolerant for SMBus interface
• High speed signal flow–thru pinout package: 54-pin LLP
(10 mm x 5.5 mm)
Applications:
• PCIe (2.5 Gbps / 5.0 Gbps)
• Will also support other AC coupled 8b/10b encoded serial standards under 5.0 Gbps
