• Manufacturer Part Number: S1M8821
• Description: Interger Rf/if Dual Pll Frequency Synthesizer
• Manufacturer: Samsung Semiconductor, Inc.

INTERGER RF/IF DUAL PLL
PIN CONFIGURATION(24-QFN, NOT TO SCALE)
NOTES:

2.
pin #10 = pin #19(internally connected).
Do not tie up Vp and V
:
noisy Vp corrupts the power source for the analog part.
Vp is the source of digital noises. The power for analog part is supplied by V
