TFF11092HN/N1X

Application Specific Clock/Timing Overview

The TFF11092HN is a Ku band frequency generator designed for low phase noise Local Oscillator (LO) circuits in VSAT transmitters and transceivers. It integrates a VCO, PLL, and output buffer within a 24-HVQFN package. The device generates RF output frequencies between 9.03 GHz and 9.22 GHz with a supply voltage of 3.0 V to 3.6 V. Typical supply current is 100 mA. Phase noise at 100 kHz offset is typically -97 dBc/Hz with a divider value of 64. It supports reference input frequencies from 35 MHz to 576 MHz and includes a lock detector output.

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix against NXP documentation to confirm packaging details such as reel size or tape configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or NXP sales offices prior to procurement.

Application Specific Clock/Timing Selection Notes

Select appropriate loop filter components based on the chosen divider setting and reference frequency as detailed in Table 5 of the datasheet. Ensure the reference source phase noise meets requirements (e.g., -149 dBc/Hz at 100 kHz offset for divider 64). Verify that the operating temperature range of -40°C to +85°C suits the application environment.
