General Description
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 single- and dual-band digital cellular systems e.g. GSM, PCN (DCS 1800) and PCS systems.
Features
■ 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
■ External or internal reference current setting for PD outputs
■ Low operating current consumption
■ Programmable power down modes
■ High input sensitivity and high input frequencies: PLL1 (RF): 2.8 GHz PLL2 (IF): 600 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
■ Switchable polarity and programmable phase detector currents
■ Fast serial 3-wire bus interface with low threshold voltage Schmitt-Trigger inputs for interfacing with low voltage baseband circuits
■ Two data registers in PLL2 for fast IF band switching
■ A programmable output port for lock detect or general porpose (VCO switch etc.).
