Profile: Micrel, Inc. is a manufacturer of integrated circuit solutions for the worldwide analog, Ethernet and high bandwidth markets. We are an ISO 9001:2000 and 14001 certified company. Our product line includes battery chargers, linear integrated circuits, current limiting power switches, and radio frequency integrated circuits. Our MIC79050 is a simple single-cell lithium-ion battery charger. It includes an on-chip pass transistor for high precision charging, and features ultrahigh precision and "zero" off mode current. Our MIC1700 is a complete reconstruction filter solution for high definition set-top boxes. The device has two independent component inputs (YPrPb or RGB), selectable via a 2-to-1 multiplexer, and a separate S-video input (Y/C). Component channel filters have a selectable cutoff frequency ( 8MHz or 36MHz) to support both standard (SD) and high definition (HD) applications. S-video filters have fixed cutoff (8MHz) to support legacy composite applications. In addition, S-video channels are summed to provide a filtered CV output for an RF modulator or VCR. All inputs are DC coupled with a 0 V to 1 V peak-to-peak range. All outputs are designed to drive 2 V peak-to-peak into AC-coupled 150 Ohm loads. This supports 1 V peak-to-peak into a 75 load with a 75 Ohm series source terminator.
