TDA7088T FM radio circuit diagram, schematic diagram
TDA7088T is a FM radio integrated block developed and produced by Philips. It uses a 16-pin dual-row flat package and an operating voltage of 3V. This circuit includes all functions of the FM radio receiving the frequency discrimination output audio signal from the antenna, and also has search tuning. Circuit, signal detection circuit, squelch circuit, and frequency locked loop FLL circuit that compresses the intermediate frequency offset. The intermediate frequency of the TDA7088T circuit is designed to be 70kHz, and the intermediate circuit does not need an intermediate frequency transformer. The intermediate frequency is selected by the internal RC intermediate frequency filter.
Fast Ethernet Media Converters transparently connect UTP copper to fiber. Our fast ethernet media converters provide an economical path to extend the distance of an existing network, the life of non-fiber based equipment, or the distance between two devices.with the DIP Switch. The DIP Switch can set the conversion mode (store and forward/ cut-through), the operate mode (full-duplex/half-duplex), operate speed (10/100M) and Link Fault Pass-through (LFP) function.
LFP (LLCF/LLR) can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net. LLCF (Link Loss Carry Forward) means when a device connected to the converter and the TP line loss the link, the converter's fiber will disconnect the link of transmit. LLR (Link Loss Return) means when a device connected to the converter and the fiber line loss the link, the converter's TP port will disconnect the link of transmit. Both can immediately alarm administrators the problem of the link media and provide efficient solution to monitor the net.
