The TLV5591 signal processor is a FLEXt signal processor that takes full advantage of the MotorolaR FLEX paging protocol. This low-current device operates at synchronous data rates of 1600, 3200, and 6400 bits per second (bps) using a 76.8 kHz oscillator. This device is readily integrated with standard off-the-shelf electronic pager components thereby reducing start-up costs associated with pager manufacturing. An industry standard serial peripheral interface (SPI) transports simultaneous bidirectional 32-bit data packets between the TLV5591 and the host processor.
