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.

DESCRIPTION
Input for Output Enable (Active low). Enables transceiver driver to transmit data on the USB bus.
When OE pin = LOW, driver circuitry is enabled.
Differential receiver output of D+ and D- input data lines. The output state of RCV is preserved and
stable during an SE0 condition.
Single-ended D+ receiver output for detection of a single-ended zero or error conditions
Single-ended D- receiver output for detection of a single-ended zero or error conditions.
Suspend input. Allows the device to enter a low power state while the USB is inactive.
Mode input. Selects between differential (V
PO
, V
MO
) and single-ended mode (V
O
, FSEO).
Supply voltage for digital I/O pins. Voltages supported: 1.65 to 3.3V.
I/O level USB detect output. Logic High indicates that a USB cable is present.
Negative USB data connection.
Positive USB data connection. In full-speed connect mode, connect to V
PU
via a 1.5kΩ resistor. Tol-
erance of this resistor is defined in the USB specification REV 1.1 & 2.0
Driver data input.
Driver data input.
Regulated supply voltage output during USB operation of V
BUS
. 1uF decoupling capacitor is
required.
Supply voltage input. Can be directly connected to USB V
BUS
.
Pull-up supply voltage. Pin function is controlled by input ENUM.

Enumerate, allows software to control connection of the external pull-up via the level translator. If
ENUM = LOW then V
