Product Description
The CM2400-05 Universal Serial Bus (USB) trans-
ceiver is fully compliant with USB specification, revi-
sions 1.1 and 2.0. It supports a speed of 12Mbits/s
(Full Speed Mode).
An internal level shifter allows interface to Application
Specific Integrated Circuits (ASICs) and Programma-
ble Logic Devices (PLDs) running at core voltages of
1.65V to 3.6V.
An internal 5V to 3.3V regulator is used to power the
CM2400-05 USB transceiver via the USB supply V
BUS
.

are bi-directional interface pins. In
one mode they function as the differential driver input
data. In another mode they function as the output of
the single ended receivers. This mode is configured by
the OE pin.
This device is ideal for portable electronic devices such
as mobile phones, digital still cameras, PDAs (Personal
Digital Assistants) and IAs (Information Appliances).
The CM2400-05 is manufactured in small form-factor
16-lead HBCC or TQFN packages to conserve board
space and is available with optional lead-free finishing.
