Samsung S1T8825B Data Sheet

The S1T8825B is a high-performance dual frequency synthesizer with two integrated high-frequency pre-scalers for RF operation up to 1.3 GHz. It 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 in a 16-TSSOP package. Serial data is transferred into the S1T8825B via a three-wire interface (CK, DATA, EN).
