1.1GHZ DUAL PLL
KB8825
INTRODUCTION
16鈭扵SSOP鈭?044
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鈥檚 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).
