TFF11084HN

www.DataSheet4U.com TFF11084HN Low phase noise LO generator for VSAT applications Rev. 1 — 12 July 2010 Objective data sheet 1. General description The TFF11084HN is a Ku band frequency generator intended for low phase noise Local Oscillator (LO) circuits for Ku band VSAT transmitters and transceivers. The specified phase noise complies with IESS-308 from Intelsat. CAUTION This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. 2. Features and benefits „ „ „ „ „ „ „ Phase noise compliant with IESS-308 (Intelsat) in combination with appropriate source LO generator with VCO range from 8.20 GHz to 8.60 GHz Input signal 32 MHz to 538 MHz Divider settings 16, 32, 64, 128 or 256 Output level −5 dBm; stability ±2 dB Third or fourth order PLL Internally stabilized voltage references for loop filter 3.
