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.
