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.  
Two single-ended receivers with hysteresis  
USB Detection of V via level translator

Stable RCV output during SE0 condition  
Low power operation  
Supports 1.65V to 3.3V I/O voltage levels  
Full industrial operating range -40 to 85 °C  
Available in small HBCC16 package  
An internal 5V to 3.3V regulator is used to power the  
CM2400-01HB USB transceiver via the USB supply  
V
. A voltage comparator has been integrated to  
BUS  
detect the V  
voltage via the level translator. This  
BUS  
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).  
Applications  
Wireless handsets  
Digital still cameras  
PDAs (Personal Digital Assistants)  
IAs (Information Appliances)  
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.
