Product Description
The CM2400-02/03/04 Universal Serial Bus (USB)
transceiver is fully compliant with the USB specification
Rev 1.1 and 2.0. It supports a speed of 12Mbits/s (Full
Speed Mode).
An internal level shifter allows interface to Application
Specific ICs (ASICs) and Programmable Logic Devices
(PLD's) running at core voltages of 1.65V to 3.6V.
The CM2400-02/03/04 features an internal 5V to 3.3V
regulator which is used to power the USB transceiver
via the USB supply V_BUS.
The CM2400-04 features a Mode Input pin (MODE)
which allows the device to operate in either single or
differential input mode.
This device is ideal for portable electronic devices such
as mobile phones, digital still cameras, PDAs (Personal
Digital Assistants) and IAs (Information Appliances).
The CM2400-02/03/04 is packaged in a small form-fac-
tor 16-lead HBCC or TSSOP package to conserve
board space.
