4 x E1/T1 Fiber Mux/De-mux over One Fiber Optic Cable

DESCRIPTION The ACS406CS comprises a chip set of two highly integrated devices, the ACS9010 and ACS4060. The ACS9010 is an analog transceiver device and the ACS4060 is a mixed signal device. FEATURES • Two chip set supporting full duplex serial data transmission up to 8.448Mbps over one fiber

1, 2, and 4k bit EEPROMs for direct connection to serial ports

• Overview The BR90 series are serial EEPROMs that can be connected directly to a serial port and can be erased and written electrically. Writing and reading is performed in word units, using four types of operation commands. Communication occurs through CS, SK, DI, and DO pins, WC pin control is

Engine Knock Signal Processor

The HIP9010 is used to provide a method of detecting premature detonation or “Knock” in automotive engines. A block diagram of this IC is shown in Figure 1. The chip alternately selects one of the two sensors mounted on the engine block. Two programmable bandpass filters process the signal from b
