ASSP Dual Serial Input PLL Frequency Synthesizer(Small Package)
MB15F76UV
DESCRIPTION
The Fujitsu MB15F76UV is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 6000MHz and a 1500MHz prescalers. Both IF and RF PLL section have a 1/4 divider. And a 16/17 or a 32/33 for the 6000MHz prescaler, and a 4/5 or a 8/9 for the 1500MHz prescaler can be selected for the prescaler that enables pulse swallow operation. The BiCMOS process is used, as a result, a supply current is typically 8.5mA typ. at 3.0V. The supply voltage range is from 2.5V to 3.6V. A refined charge pump supplies well-balanced output current with 1.5mA and 6mA selectable by serial data. Fast locking is acheived for adopting the new circuit. The new package(BCC18) decreases a mount area of MB15F76UV about 50% comparing with the former BCC20(for dual PLL). MB15F76UV is ideally suited for wireless communications, such as W-LAN.
FEATURES
