Product Description

2.1 Overview

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.

2.2 Features

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

(fmax ~ 10 MHz)

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

(fmax ~ 10 MHz)

Switchable polarity and phase detector current programmable

2 Multifunction outputs frn, fvn outputs of the R- and N/A- counters for test

Output port (e.g. for standby of the prescaler)

External current setting for PD output

Lock detect output with quasidigital lock detect
