Product Description
The CM2400-01HB Universal Serial Bus (USB) trans-
ceiver 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 IC's (ASIC's) and Programmable Logic
Devices (PLD's) running at core voltages of 1.65V to
3.3V.
An internal 5V to 3.3V regulator is used to power the
CM2400-01HB USB transceiver via the USB supply
V_BUS. A voltage comparator has been integrated to
detect the V_BUS voltage via the level translator. This
insures compatibility with the processor’s core voltage
and outputs to the USB_DET pin. A high level on the
USB_DET output indicates that an active USB cable is
attached. Single and differential input modes are
selectable by a mode input pin (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 CM2400-01HB is packaged in a small form-factor
16-lead HBCC package to conserve board space.
