3.4.1
General information
The PMB2341 consists of a dual band single PLL. The device is designed to work in
mobile communication systems and can handle VCO input frequencies up to 2.5 GHz.
3.4.2
PLL
The PLL in the PMB 2341 consists of a high frequency bipolar configurable 32/33 or 64/
65 dual modulus prescaler, an A- and a N-counter with dual modulus control logic, a
reference- (R-) counter, and a phase detector with charge pump output with
programmable output current drive capability. The counter and mode settings of the
synthesizer are programmed via a serial 3-wire interface.
The reference frequency is applied at the RI-input and divided by the PLL
’
s R-counter.
Its maximum value is specified to be 100 MHz. The VCO
’
s RF input signal is divided by
the bipolar prescaler with a programmable 32/33 or 64/65 divider ratio and the following
programmable A/N-counters. For a wide range of divider ratios, both N and R counter
can be programmed from 3 to 4095 .
The phase and frequency detectors with the charge pumps have a linear operating range
without dead zone for very small phase deviations.
The operating modes allow the selection of 4 different charge pump output currents,
polarity setting of the phase detector, 2 standby modes and the conrol of the multi-
functional output port MFO.
