IEEE 1394 Single And Dual Port FireWire Protective Circuits

The IEEE 1394, which is also called FireWire by Apple, is an interface standard for high-speed serial bus for connecting devices to a personal computer. Like USB, IEEE 1394 is a serial bus that uses twisted-pair wiring to move data around. However, USB is limited to 12Mbps, IEEE 1394 currently handles up to 400Mbps. The reference design illustrates single and dual port FireWire protective circuits. The single-port FireWire protective circuit is designed using the MAX5943A, while the dual-port FireWire protective circuit utilizes the MAX5944.

Multiple-input, Multiple-output (MIMO) Receiver

This design features an antenna that is commonly used in telecommunications such as 4th generation GSM standard. The fourth-generation (4G) Long-Term Evolution (LTE) is a standard for high-speed wireless communication of data for mobile phones. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together. These 4G wireless communications networks are predicted to depend on MIMO receiver technologies. These 4G operators and customers are expecting faster data rates and wider bandwidths, both of which place demands on new receiver designs.

F0480 Matched Broadband RF VGA with Glitch-Free and Zero-Distortion


The F0480 is a RF Digital Variable Gain Amplifier (RF DVGA) with a wide bandwidth of 400MHz to 2700MHz. The use of glitch-free and zero-distortion technologies reduce attenuation overshoot during attenuation state changes. Combining silicon glitch-free DSA and a zero distortion RF amplifier in a single compact QFN package the F0480 of IDT provides very high reliability. It features a typical maximum gain of 13dB with a noise figure of 4dB and a gain adjustment of 23dB in 1dB steps designed to operate with a single 5V supply. It offers +41dBm output IP3 using 100mA of current.
