ML5800

www.DataSheet4U.com ML5800 5.8GHz Low-IF 1.5Mbps FSK Transceiver FINAL Datasheet GENERAL DESCRIPTION The ML5800 is a high integration 5.8GHz Frequency Shift Keyed (FSK) transceiver that integrates all frequency generation, receive, and transmit functions required to realize a digital cordless telephone. Only a power amplifier (PA) and antenna switch are required to form a complete 5.8GHz digital radio. The ML5800 operates in the 5.725 to 5.850 GHz unlicensed ISM band. It can be used to implement both Direct Sequence and Frequency Hopping Spread Spectrum radios. The ML5800 contains a dual-conversion low-IF receiver with all channel selectivity on chip. IF filtering, IF gain, and demodulation are performed on chip eliminating the need for any external IF filters or production tuning. A post detection filter and a data slicer are integrated to complete the receiver. The ML5800 transmitter uses an adjustment-free twoport closed loop modulator, which modulates the onchip VCO with filtered data. An upconversion mixer and buffer/predriver produces output of 0dBm at 5.8GHz. A fully integrated 3.9GHz fractional synthesizer is used in both receive and transmit modes. Power supply regulation is included in the ML5800, providing circuit isolation and consistent performance over supply voltages between 2.7V-3.6V. § § § § § § § § § § § § § FEATURES High Integration 5.8GHz FSK Transceiver High data rate - 1.536Mbps Low-IF receiver eliminates external IF filters Fully integrated IF filters...
