SATA/SAS MiniSAS4X Cable Extender Demo Kit
General Description:
The DS64BR401EVK – miniSAS4X cable extender demonstration kit provides a complete cable
extension solution using National’s DS64BR401 – Quad Bi-directional Cable/Backplane Extender with
Equalization and De-emphasis.
MiniSAS4X right angle I-PASS Molex receptacle connectors are used as the input and the output
connections for SATA/SAS disk drive storage application. Adaptor board which provides connection
from mini SAS4X (26-pin external) to mini SAS4Xi (36-pin internal) is provided to allow easy straight
forward connection to existing hardware.
Features:
• Quad lane bi-directional transceiver up to 6.4 Gbps rate
• Signal conditioning on input and output for extended reach
• Adjustable receive equalization up to +33 dB gain
• Adjustable transmit de-emphasis up to −12 dB
• Adjustable transmit VOD (600 mVp-p to 1200 mVp-p)
• <0.25 UI of residual DJ at 6.4 Gbps with 40” FR4 trace
• Automatic de-emphasis scaling based on rate detect
• SATA/SAS: OOB signal pass-through,
<3 ns (typ) envelope distortion
• 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:
• SATA (1.5 Gbps / 3.0 Gbps / 6.0 Gbps)
• SAS (3.0 Gbps / 6.0 Gbps)
