DESCRIPTION

The Fujitsu MB15F72UV 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.

FEATURES

? High frequency operation : RF synthesizer : 1300 MHz Max

: IF synthesizer : 350 MHz Max

? Low power supply voltage : VCC = 2.4 V to 3.6 V

? Ultra low power supply current : ICC = 2.5 mA Typ

(VCC = 2.7 V, SWIF = SWRF = 0, Ta = +25 °C, in IF, RF locking state)

? Direct power saving function : Power supply current in power saving mode

Typ 0.1 μA (VCC = 2.7 V, Ta = +25 °C)

Max 10 μA (VCC = 2.7 V)

? Software selectable charge pump current : 1.5 mA/6.0 mA Typ

? Dual modulus prescaler : 1300 MHz prescaler (64/65 or 128/129 ) /350 MHz prescaler (8/9 or 16/17)

? 23 bit shift resister

? Serial input 14-bit programmable reference divider : R = 3 to 16,383

? Serial input programmable divider consisting of :

- Binary 7-bit swallow counter : 0 to 127

- Binary 11-bit programmable counter : 3 to 2,047

? On?chip phase control for phase comparator

? On?chip phase comparator for fast lock and low noise

? Built-in digital locking detector circuit to detect PLL locking and unlocking.

? Operating temperature : Ta = ?40 °C to +85 °C

? Serial data format compatible with MB15F72UL

? Ultra small package BCC18 (2.4 mm × 2.7 mm × 0.45 mm)
