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.

CM2400-02/03/04
PRELIMINARY
Functional Description
The CM2400-02/03/04 USB Transceiver supports 3 dif-
ferent power supply configurations, which can be con-
figured dynamically.
Table 1
details the various
configurations. In Normal Mode the internal regulator
produces 3.3V from V
BUS
to power the internal drivers
and receivers associated with the USB protocol.
Table 1: Power Supply Connections
There are three power supply configurations for the
CM2400-02/03/04: Normal mode, Disable mode and
Sharing mode. These three modes can be changed
dynamically.
Normal mode occurs when the V
CC
and V
BUS
inputs
are both connected to a source. V
BUS
is tied to a 5V
source for 5V operation. The internal regulator of the
CM2400-02/03/04 provides 3.3V output on V
REG
. The
V
CC
input is connected to an independent source that
can range from 1.65V to 3.6V.
When V
CC
is not connected and V
BUS
is connected,
the device is in Disable mode. The D+ and D- pins are
in tri-state and power consumption drops to a suspend
state level.
In Sharing mode, V
CC
is connected while V
BUS
is
below 3.6V. The D+ and D- pins are in tri-state and the
CM2400-02/03/04 allows external signals (
3.6V) to
share these two lines. The CM2400-02/03/04 is
designed to draw almost zero current from the D+ and
D- lines while in sharing mode. In this mode, V
P
and
V
M
are driven high while RCV and USB_DET are
driven low.
In Disable and Sharing Mode, all input/output pins fol-
low the states defined in
Table 2
.
Table 2: Pin States in Disable or Sharing Mode
Table 3
lists the functions of the modes associated with
suspend and OE pins. When Suspend is low and OE is
high, signal levels on D+ and D- are determined by
other USB devices and pull-up/down resistors. In Sus-
pend Mode (SPND = HIGH) the differential receiver is
inactive and output RCV is always LOW. Out of sus-
pend signaling is detected via the single-ended receiv-
ers V
P
and V
M
. During suspend and while the output is
still enabled (OE = LOW), D+ and D- lines are driven to
their intended states.

CM2400-02/03/04
PRELIMINARY
Functional Description (cont'd)
Detailed in
Table 4
and
Table 5
are the operating
modes for the CM2400-02/03/04. The CM2400-02 fea-
tures a fixed, single-ended input operating mode which
is summarized in
Table 4
. The CM2400-03 features a
differential-pair input operating mode which is summa-
rized in
Table 5
. The CM2400-04 input mode is select-
able via the MODE input.
Table 4
and
Table 5
summarize both operating modes for the CM2400-04.
On the CM2400-02, the two driver inputs function as
V
O
and FSE0 inputs. On the CM2400-03, the driver
inputs function as V
PO
and V
MO
. On the CM2400-04,
when the MODE input is HIGH, differential-pair input
mode is selected and the two driver inputs function as
V
PO
and V
MO
. When MODE is LOW, the single-ended
input data interface mode is selected and the two driver
inputs function as V
O
and FSE0.
Table 4: Single-ended Input Operating Mode,
CM2400-02 and CM2400-04 in Single-ended
Input Mode (OE = L)
Table 5: Differential-pair Input Operating Mode,
CM2400-03 and CM2400-04 in Differential-pair
Input Mode (OE = L)
Table 6
details the receiving function when OE is HIGH
(driver disabled). RCV denotes the signal level on the
output RCV just before an SE0 state occurs. This level
is stable during the SE0 period.
* Denotes RCV is stable in last state before SE0 condition.
Table 6: Receiving Function (SPND = L)
A regulator bypass option can be utilized by shorting
VBUS to VREG and connecting to a 3.3v supply.
