PRELIMINARY SPECIFICATION (V1.5)

FREQUENCY SYNTHESIZER

KB8821/22/23

INTRODUCTION

The KB8821/22/23 are high performance dual frequency syn-

thesizers with integrated prescalers designed for RF operation

up to 1.2GHz/2.0GHz/2.5GHz and IF operation up to 520MHz.

The KB8821/22/23 contain dual-modulus prescalers. The RF

synthesizer adopts a 64/65 or an 128/129 prescaler(32/33 or

64/65 for the KB8823) and the IF synthesizer adopts an 8/9 or

a 16/17 prescaler.

20-TSSOP-225

Using a proprietary digital phase-locked-loop technique, the

KB8821/22/23 have linear phase detector characteristic and

can be used for very stable, low noise local oscillator signal.

Supply voltage can range from 2.7V to 4.0V. The KB8821/22/

23 are now available in a 20-TSSOP/24-QFN package.
