INTERGER RF/IF DUAL PLL

S1M8821/22/23

INTRODUCTION

20-TSSOP-BD44

The S1M8821/22/23 is a high performance dual frequency

synthesizer with integrated prescalers designed for RF operation up

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

The S1M8821/22/23 contains dual-modulus prescalers. The RF

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

the S1M8823) and the IF synthesizer adopts an 8/9 or a 16/17

prescaler.

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

S1M8821/22/23 has 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 S1M8821/22/23 is now available in

a 20-TSSOP/24-QFN package.
