KB8823, FREQUENCY SYNTHESIZER
Pin No 1 Symbol VDD1 I/O Description KB8821/22/23 Power supply voltage input for the RF PLL part.
V DD1 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.

PRELIMINARY SPECIFICATION (V1.5) FREQUENCY SYNTHESIZER INTRODUCTION The KB8821/22/23 are high performance dual frequency synthesizers with integrated prescalers designed for RF operation up to 1.2GHz/2.0GHz/2.5GHz and IF operation up to 520MHz.
The KB8821/22/23 contain dual-modulus prescalers.
The RF synthesizer adopts a 64/65 or an 128/129 prescaler(32/33 or 64/65 for the KB8823) and the IF synthesizer adopts an 8/9 or a 16/17 prescaler.
Using a proprietary digital phase-locked-loop technique,
