Wireless Components
2.1 Overview
2.2 Features
The PMB 2304R PLL is a high speed CMOS IC, especially designed for use in
battery powered radio equipment and mobile telephones and serves as a func-
tional replacement of the PMB 2307R. The primary applications are in digital
cellular and cordless systems e.g. GSM 900/1800/1900 and DECT systems.
The wide range of dividing ratios also allows application in analog systems.






























Low operating current consumption (typically 3.5 mA)
High input sensitivity, high input frequencies (220 MHz)
Extremely fast phase detector without dead zone
Linearization of the phase detector output by current sources
Synchronous programming of the counters (N-, N/A-, R-counters) and
system parameters
Fast modulus switchover for 65-MHz operation
Switchable modulus trigger edge
Serial control (3-wire bus: data, clock, enable) for fast programming
(
Large dividing ratios for small channel spacing
A counter 0 to 127
N counter 3 to 16.383
R counter 3 to 65.535
Serial control (3-wire bus: data, clock, enable) for fast programming
(
Switchable polarity and phase detector current programmable
2 Multifunction outputs
Output port (e.g. for standby of the prescaler)
External current setting for PD output
Lock detect output with quasidigital lock detect
