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.

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 con-
ditions
Single-ended D- receiver output for detection of a single-ended zero or error con-
ditions.
Suspend input. Allows the device to enter a low power state while the USB is inac-
tive.
Mode input (CM2400-04). Selects between differential (V
PO
, V
MO
) and single-
ended mode (V
O
, FSEO).
Ground input (CM2400-02/03).
Supply voltage for digital I/O pins. Voltages supported: 1.65 to 3.6V.
Speed Input. If SPEED is logic '1', selects full speed. If SPEED is logic '0', selects
low speed. SPEED changes slope rise and fall time on D+ and D-.
Negative USB data connection.
Positive USB data connection. In full-speed connect mode, connect to V
PU
via a
1.5kΩ resistor. Tolerance 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
. 1µF 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.
