S1M8823 INTERGER RF/IF DUAL PLL

Pin No (20TSSOP) 1 Pin No (24QFN) 24 Symbol VDD1 I/O Description Power supply voltage input for the RF PLL part. VDD1 must equal VDD2. In order to reject supply noise, bypass capacitors must be placed as close as possible to this pin and be connected directly to the ground plane. No connection. Powe.

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.
