MIC2551A-2.5 - USB Transceiver

Download the MIC2551A-2.5 datasheet PDF. This datasheet also covers the MIC2551A-25 variant, as both devices belong to the same usb transceiver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC2551A is a single chip transceiver that complies with the physical layer specifications of the Universal Serial Bus (USB) 2.0.

It supports both full speed (12Mbps) and low speed (1.5Mbps) operation and introduces superior edge rate control, producing crisper eye diagrams.

Key Features

  • ±15kV ESD protection on VBUS, D+ and D.
  • Smaller 2.5mm × 2.5mm MLF™ package.
  • USB 1.1 and 2.0 compliant transceiver (full speed 12Mbs and low speed - 1.5Mbps) operation.
  • Separate I/O supply with operation down to 1.6V.
  • Integrated speed select termination supply.
  • Very-low power consumption to meet USB suspend current requirements.
  • No power supply sequencing requirements.
  • Software controlled enumeration.

MIC2551A-2.5 Micrel, Inc. MIC2551A-2.5 USB Transceiver www.DataSheet4U.com General Description The MIC2551A is a single chip transceiver that complies with the physical layer specifications of the Universal Serial Bus (USB) 2.0. It supports both full speed (12Mbps) and low speed (1.5Mbps) operation and introduces superior edge rate control, producing crisper eye diagrams. This in turn, eases the task of passing USB compliance testing. A unique, patented, dual supply voltage operation allows the MIC2551A to reference the system I/F I/O signals to a supply voltage down to 1.6V while independently powered by the USB VBUS. This reduces system operating current and allows the system to operate at its core voltage without additional buffering logic. MIC2551A-2.
