DS64MB201에 대한 설명
The DS64MB201 is a dual lane 2:1 multiplexer and 1:2 switch or fan-out buffer with signal conditioning suitable for SATA/SAS and other high-speed bus applications up to 6.4 Gbps. The device performs both receive equalization and transmit de-emphasis, allowing maximum flexibility of physical placement within a system. The receiver's continuous time linear equalizer (CTLE) provides a boost of up to +33 dB at 3 GHz and is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect medium. The transmitter features a programmable output de-emphasis driver and allows amplitude voltage levels to be selected from 600 mVp-p to 1200 mVp-p to suit multiple application scenarios. The signal conditioning settings are programmable via control pin settings or SMBus interface.
To enable seamless upgrade from SAS/SATA 3.0 Gbps to 6.0 Gbps data rates without compromising physical reach, DS64MB201 automatically detects the incoming data rate and selects the optimal de-emphasis pulse width. The device detects the out-of-band (OOB) idle and active signals of the SAS/SATA specification and passes through with minimum signal distortion.
