INTERGER RF/IF DUAL PLL
S1M8821/22/23
1
INTRODUCTION
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.
