Final version ( 99.4.30 )
INTRODUCTION
The KB8825 is a high performance dual frequency synthesizer with
two integrated high frequency pre-scalers for RF operation up to 1.1
GHz.
The KB8825 is composed of modulus pre-scalers providing 64 and
66, no dead-zone PFD, selectable charge pump current, selectable
power down mode circuits, lock detector output, and loop filter
’
s time
constant switch.
It is fabricated using the ASP5HB Bi-CMOS process and is available
16-TSSOP with surface mount plastic packaging. Serial data is trans-
ferred into the KB8825 via three-wire interface (CK, DATA, EN).
FEATURES

2.7 ~ 3.6V ( 550MHz ~ 1.1GHz Operating )
Modulus pre-scaler: 64 / 66
No dead-zone PFD
Colpitt type local oscillation
Selectable charge pump current
Selectable power down mode
TSSOP 16-pin package (0.65 mm pitch)
