General Description

The PMB 2304R PLL is a high speed Package:

CMOS IC, especially designed for use

in battery powered radio equipment

and mobile telephones and serves as a

functional 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.

Features

Low operating current consumption
Large dividing ratios for small

(typically 3.5 mA)

channel spacing

High input sensitivity, high input

frequencies (220 MHz)

A counter 0 to 127

N counter 3 to 16.383

R counter 3 to 65.535

Extremely fast phase detector

without dead zone

Serial control (3-wire bus: data,

clock, enable) for fast programming

Linearization of the phase detector

(fmax ~ 10 MHz)

output by current sources

Switchable polarity and phase

Synchronous programming of the

detector current programmable

counters (N-, N/A-, R-counters)

and system parameters

Fast modulus switchover for

2 Multifunction outputs

frn, fvn outputs of the R- and

N/A- counters for test

65-MHz operation

Output port

Switchable modulus trigger edge

(e.g. for standby of the prescaler)

Serial control (3-wire bus: data,
External current setting for PD

clock, enable) for fast programming output

(fmax ~ 10 MHz)

Lock detect output with quasidigital

lock detect

Application
GSM 900 / 1800 / 1900

DECT

Analog systems
