MB15F78SP - Dual Serial Input PLL Frequency Synthesizer

General Description

The Fujitsu MB15F78SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2550 MHz prescaler and a 1200 MHz prescaler.

Key Features

  • High frequency operatio.
  • : RX synthesizer : 2550 MHz max : TX synthesizer : 1200 MHz max Low power supply voltage : VCC = 2.4 to 3.6 V Ultra Low power supply current : ICC = 5.5 mA typ. (VCC = Vp = 2.7 V, Ta = +25°C, SWTX = SWRX = 0, in TX/RX locking state) Direct power saving function : Power supply current in power saving mode Typ. 0.1 µA (VCC = Vp = 2.7 V, Ta = +25°C), Max. 10 µA (VCC = Vp = 2.7 V) Software selectable charge pump current: 1.5 m.

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-21364-3E ASSP Dual Serial Input PLL Frequency Synthesizer MB15F78SP s DESCRIPTION The Fujitsu MB15F78SP is a serial input Phase Locked Loop (PLL) frequency synthesizer with a 2550 MHz prescaler and a 1200 MHz prescaler. A 32/33 or a 64/65 for the 2550 MHz prescaler, and a 16/17 or a 32/33 for the 1200 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 5.5 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.
