2.1 Overview
The PMB 2349 is a RF/IF Dual-PLL frequency synthesizer implemented in Infi-
neon’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.
2.2 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.).
