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.

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.
