MAX4889C - 2.5/5.0/8.0Gbps PCIe Passive Switches

Download the MAX4889C datasheet PDF. This datasheet also covers the MAX4889B variant, as both devices belong to the same 2.5/5.0/8.0gbps pcie passive switches family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX4889B/MAX4889C high-speed passive switches route PCI Express® (PCIe) data between two possible destinations in desktop or notebook PCs.

The MAX4889B/MAX4889C are quad double-pole/doublethrow (4 x DPDT) switches ideal for switching four half lanes of PCIe data between two destinations.

Key Features

  • Single +3.3V Power-Supply Voltage.
  • Support PCIe Gen I, Gen II, and Gen III Data Rates.
  • Supports SAS I, SAS II, and SAS 6.0Gbps (MAX4889C).
  • Superior Return Loss Better than -10dB (typ) at 5.0GHz.
  • Small 3.5mm x 9.0mm, 42-Pin TQFN Package.
  • Industry-Standard Pinouts Ordering Information PART TEMP RANGE PIN-.

19-4148; Rev 2; 8/10 EVAALVUAAILTAIOBNLEKIT 2.5/5.0/8.0Gbps PCIe Passive Switches MAX4889B/MAX4889C General Description The MAX4889B/MAX4889C high-speed passive switches route PCI Express® (PCIe) data between two possible destinations in desktop or notebook PCs. The MAX4889B/MAX4889C are quad double-pole/doublethrow (4 x DPDT) switches ideal for switching four half lanes of PCIe data between two destinations. The MAX4889B/MAX4889C feature a single digital control input (SEL) to switch signal paths. The MAX4889C is intended for use in systems (e.g., SAS) where both the input and output are capacitively coupled, and provides a 10µA (typ) source current and a 60kΩ (typ) internal biasing resistor to GND at the _OUT_ terminals.
