Description
The Fujitsu MB15F72UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 1300 MHz and a 350 MHz prescalers. A 64/65 or a 128/129 for the 1300 MHz prescaler, and a 8/9 or a 16/17 for the 350 MHz 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 2.5 mA at 2.7 V. The supply voltage range is from 2.4 V to 3.6 V. A refined charge pump supplies well-balanced output current with 1.5 mA and 6 mA selectable by serial data. The data format is the same as the previous one MB15F02SL, MB12F72SP. Fast locking is achieved for adopting the new circuit.
The new package (BCC20) decreases the mount area of MB15F72UL by more than 30% compared with the former BCC16 (for dual PLL).
MB15F72UL is ideally suited for wireless mobile communications, such as CDMA..
Features
| High frequency operation: | RF synthesizer : 1300 MHz Max. IF synthesizer : 350 MHz Max. |
| Low power supply voltage: | VCC = 2.4 to 3.6 V ICC = 2.5 mA Typ. |
| Ultra low power supply current: | (VCC = Vp = 2.7 V, SWIF = SWRF = 0, Ta = +25 °C, in IF, RF locking state) |
