Description

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.

S1T8825B is fabricated using the ASP5HB Bi-CMOS process and is available 16-TSSOP with surface mount plastic packaging. Serial data is transferred into the S1T8825B via three-wire interface (CK, DATA, EN).
