Universal Serial Bus Transceiver

www.DataSheet4U.com CM2400-01 Universal Serial Bus Transceiver with Level Translator Features • • • • • • • • • • • • Complies with USB Specification Rev 1.1 & 2.0 Supports Full Speed Mode (12Mbit/sec.) Integrated 5V to 3.3V regulator Used as a USB device transceiver VBUS disconnection indication through VP, VM Two single-ended receivers with hysteresis USB Detection of VBUS 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 Product Description The CM2400-01HB 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 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 VBUS. A voltage comparator has been integrated to detect the VBUS 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.

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 (VPO, V MO) and single-ended mode (VO, 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 VPU 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 VBUS. 1uF decoupling capacitor is required. Supply voltage input. Can be directly connected to USB VBUS. Pull-up supply voltage. Pin function is controlled by input ENUM. © 2003 California Micro Devices Corp. All rights reserved. 2 430 N.
