Package The PMB 2349 is a RF/IF Dual-PLL frequency synthesizer implemented in Infineon’s 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. Primary applications are P-VQFN-24-3 single- and dual-band digital cellular systems e.g. GSM,.
Operation range 2.7 to 5.0 V Ultra low phase noise Ultra low spurious Faster lock-in times New bipolar power modes New programmable Reference Amplifier rent setting for PD outputs 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 External or internal reference cur- Switchable polarity and programmable phase detector currents Low operating current consumption Fast serial 3-wire bus interface with low threshold.
