Product Information

The Fujitsu MB15F73UL is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2250 MHz and a 600 MHz prescalers. A 64/65 or a 128/129 for the 2250 MHz prescaler, and a 8/9 or a 16/17 for the 600 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 3.2 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 date. The data format is the same as the previous one MB15F03SL, MB15F73SP. Fast locking is achieved for adopting the new circuit. The new package (BCC20) decreases a mount area of MB15F73UL more than 30% comparing with the former BCC16 (for dual PLL) . MB15F73UL is ideally suited for wireless mobile communications, such as GSM and PCS.


High frequency operation : RF synthesizer : 2250 MHz Max.
IF synthesizer : 600 MHz Max.
Low power supply voltage : VCC = 2.4 to 3.6 V
Ultra low power supply current : ICC = 3.2 mA Typ.
(VCC = Vp = 2.7 V, Ta = +25 C, SWIF = SWRF = 0 in IF/RF locking state)
Direct power saving function : Power supply current in power saving mode
Typ. 0.1 mA (VCC = Vp = 2.7 V, Ta = +25 C)
Max. 10 mA (VCC = Vp = 2.7 V)
Software selectable charge pump current : 1.5 mA/6.0 mA Typ.
Dual modulus prescaler : 2250 MHz prescaler (64/65 or128/129) /600 MHz prescaler (8/9 or 16/17)
