PMB2347 - RF/IF Double PLL Frequency Synthesizer

The PMB 2347 is a RF/IF double PLL Package frequency synthesizer implemented in Infineon’ high speed BiCMOS technology B6HFC.

The device contains two PLLs with integrated prescalers especially designed for use in battery powered radio equipment and mobile telephones.

• Operation range 2.7 to 5.0 V Low operating current consumption Programmable power down modes High input sensitivity and high input frequencies: PLL1 (RF): 2.8 GHz PLL2 (IF): 500 MHz Programmable dual modulus prescaler divide ratio: PLL1: 1:64/65 or 1:32/33 PLL2: 16/17 or 1:8/9 Dividing ratios: A counters: PLL1: 0 to 63 PLL2: 0 to 15 N counters: PLL1: 3 to 16,383 PLL2: 3 to 16,383 R counters 3 to 16,383 for PLL1 and PLL2 Fast phase detectors and charge pump outputs without dead zone s s High ph.
