1.1GHZ DUAL PLL

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). By Samsung Semiconductor, Inc.
