1.3GHZ DUAL PLL
INTRODUCTION
The S1T8825B is a high performance dual frequency synthesizer with
two integrated high frequency pre-scalers for RF operation up to 1.3
GHz.
The S1T8825B 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 S1T8825B via three-wire interface (CK, DATA, EN).
