S1M8822 - INTERGER RF/IF DUAL PLL

Download the S1M8822 datasheet PDF. This datasheet also covers the S1M8821 variant, as both devices belong to the same interger rf/if dual pll family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • High operating frequency dual synthesizer.
  • S1M8821 : 0.1 to 1.2GHz (RF)/ 45 to 520MHz (IF).
  • S1M8822 : 0.2 to 2.0GHz (RF)/ 45 to 520MHz (IF).
  • S1M8823 : 0.5 to 2.5GHz (RF)/ 45 to 520MHz (IF).
  • Very low current consumption(8821:3.5mA, 22:4.5mA, 23:5.5mA) Operating voltage range : 2.7 to 4.0V Selectable power saving mode(Icc=1uA typical @3V) Dual modulus prescaler : S1M8821/22 S1M8823 S1M8821/22/23 No dead-zone PFD Variable c.

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 www.DataSheet4U.com 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. 24-QFN-3.5×4.
