TFF11139HN/N1,118

Application Specific Clock/Timing Overview

The TFF11139HN is a Ku band frequency generator designed for low phase noise Local Oscillator (LO) circuits in VSAT transmitters and transceivers. It operates with a supply voltage of 3V to 3.6V and draws up to 130 mA. The device generates an RF output frequency between 13.80 GHz and 14.10 GHz using a third or fourth order PLL. It accepts reference input frequencies from 54 MHz to 881 MHz and supports divider settings of 16, 32, 64, 128, or 256. The output level is -6 dBm with ±2 dB stability. Phase noise complies with IESS-308 standards when paired with appropriate sources.
