Description
The S-7760A is a programmable port controller IC comprised of an E2PROM, a control circuit for data output, a circuit to prevent malfunction caused by low power supply voltage and others.
This IC operates at 400 kHz and interfaces with exteriors via I2C-bus, controls an 8ch digital output with a serial signal.
Among the digital output ports of 8 channels, the lower 4 channels have a timer function so that at each port, users are able to set the default value and inverted delay time. In the higher 4 channels, setting the fixed output is available at each port. The default value is maintained despite power-off because this IC has an E2PROM. The S-7760A is able to be used to control ON/OFF for the chips surrounding MPU and to output the default data that devices undamentally have.

Product Description
California Micro Devices’ CM1240 is a four channel ESD protection array. Three channels of the CM1240 are low voltage (LV) diodes, which have a capacitance of 7pF enabling them to protect high speed I/O ports while providing robust ESD protection. The other channel of the CM1240 is a high voltage (HV) diode which has a capacitance of 25pF enabling it to protect
power supply inputs or OLED power rails, etc.
The parts integrate avalanche-type ESD diodes, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD protection diodes are designed and characterized to safely dissipate ESD strikes of 8kV, the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges of greater than 16kV.
This device is particularly well suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package format and easy-to-use pin assignments. In particular, the CM1240 is ideal for protecting USB or mini USB ports operating at full speed (12Mbps).
The CM1240 is available in a space saving, low profile, lead-free TDFN-8 or SOT-563 package.

Description
The FSUSB42 is a bi-directional, low-power, two-port, Hi-Speed, USB2.0 switch. Configured as a double-pole, double-throw switch (DPDT) switch, it is optimized for switching between two Hi-Speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source.
The FSUSB42 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference.
The FSUSB42 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the SEL pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the generalpurpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.

The Intel® LXT9785 and Intel® LXT9785E are 8-port Fast Ethernet PHY Transceivers supporting IEEE 802.3 physical layer applications at 10 Mbps and 100 Mbps. These devices provide Serial/Source Synchronous Serial Media Independent Interfaces (SMII/SS-SMII) and Reduced Media Independent Interface (RMII) for switching and other independent port applications. The LXT9785 and LXT9785E are identical except for the IP telephony features included in the LXT9785E transceiver. The LXT9785E is an enhanced version of the LXT9785 that detects Data Terminal Equipment (DTE) requiring power from the switch over a CAT5 cable. The system uses the information collected by the LXT97985E to apply power if the DTE at the far end requires power over the cable, such as an IP telephone.

Each network port can provide a twisted-pair (TP) or Low-Voltage Positive Emitter Coupled Logic (LVPECL) interface. The twisted-pair interface supports 10 Mbps and 100 Mbps (10BASE-T and 100BASE-TX) Ethernet over twisted-pair. The LVPECL interface supports 100 Mbps (100BASE-FX) Ethernet over fiber-optic media.

The LXT9785/LXT9785E provides three discrete LED driver outputs for each port. The devices
support both half-duplex and full-duplex operation at 10 Mbps and 100 Mbps and require only a
single 2.5 V power supply.

Applications
* Enterprise switches
* IP telephony switches
* Storage Area Networks
* Multi-port Network Interface Cards (NICs)

Product Features
* Eight IEEE 802.3-compliant 10BASE-T or 100BASE-TX ports with integrated filters.
