General Description
The PMB 2349 is a RF/IF Dual-PLL
frequency synthesizer implemented in
Infineon’s high speed BiCMOS tech-
nology 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 cur-
rent 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 program-
mable phase detector currents
Fast serial 3-wire bus interface with
low threshold voltage Schmitt-Trig-
ger 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.).
