$Features & Applications

Micrel Inc., is a leading manufacturer of IC solutions for the worldwide analog, Ethernet and high bandwidth markets. The Company's products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high speed communication, clock management, Ethernet switch and physical layer transceiver integrated circuits.

The MIC2550A is a single-chip transceiver that complies with the physical layer specifications for Universal Serial Bus (USB). It supports full-speed (12Mbps) and low-speed (1.5Mbps) operation and introduces superior edge rate control to produce crisper eye diagrams. As a result, the task of passing USB compliance testing is made easier. A unique, patented, dual supply voltage operation allows the MIC2550A to reference the system I/F I/O signals to a supply voltage down to 2.5V while independently powered by the USB VBUS. This allows the system interface to operate at its core voltage without addition of buffering logic and also reduce system operating current.


  • Compliant to USB Specification Revision 2.0 for low-speed (1.5Mbps) and full-speed (12Mbps) operation
  • Compliant to IEC-61000-4.2 (Level 2)
  • Operation down to 2.5V
  • Dual supply voltage operation
  • Integrated speed-select termination supply
  • Very low power consumption meets USB suspend-current requirements


  • Personal digital assistants (PDA)
  • Palmtop computers
  • Cellular telephones
The MIC2550AYML25 TR comes in a 16 pin MLF™ package and is available on a 5000 piece reel.
