Description

The Fujitsu MB15F74UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 4000 MHz and a 2000 MHz prescalers. A 64/65 or a 128/129 for the 4000 MHz prescaler, and a 32/33 or a 64/65 for the 2000 MHz prescaler can be selected for the prescaler that enables pulse swallow operation.

The BiCMOS process is used in MB15F74UL, as a result a supply current is typically 9.0 mA at 3.0 V. The supply voltage range is from 2.7 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 mA and 6 mA selectable by serial date. The pin assignments are the same as MB15F78UL. Fast locking is achieved for adopting the new circuit.

The new package (BCC20) decreases a mount area of MB15F74UL more than 30% comparing with the former BCC16 (for dual PLL) .
