Overview
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 com used for very stable, low noise local oscillator signal.
Supply voltage can range from 2.
7V to 4.
0V.
