DS125MB203SQ is a dual-port 2:1 multiplexer and 1:2 switch or fan-out buffer with signal conditioning, suitable for 10GE, 10G-KR (802.3ap), Fibre Channel, PCIe, wireless bandwidth, SATA3/SAS2, and other high-speed bus applications.

DS125MB203SQ – The receiver's Continuous Timeline Linear Equaliser (CTLE) provides the necessary boost performance to compensate for up to 30 inches of FR-4 or 8M cable (AWG-24) at 12.5Gbps. This on-chip feature eliminates the need for external signal conditioning. The transmitter features programmable amplitude voltage levels selectable from 600 mVp-p to 1300 mVp-p, while achieving up to 12dB of de-emphasis.

The DS125MB203SQ can be configured to support PCIe, SAS/SATA, 10G-KR, or other signal transmission protocols. When operating in 10G-KR and PCIe Gen 3 modes, the DS125MB203SQ transparently permits the host controller and endpoint to optimise the entire link and negotiate transmit equalisation coefficients. This seamless management of the link negotiation protocol ensures system-level interoperability and minimises latency.

DS125MB203SQ – This programmable configuration can be applied via pin settings, SMBus (I²C) protocol, or directly loaded from an external EEPROM. When operating in EEPROM mode, configuration information is automatically loaded at power-up, eliminating the need for an external microcontroller or software driver.

DS125MB203SQ Product Features:
12.5Gbps dual-channel 2:1 multiplexer, 1:2 switch or fan-out
Total power consumption as low as 390mW (typical)
Advanced Signal Conditioning Features:
Receive equalisation up to 30dB at 6.25GHz frequency
