Product details
Overview
TFF1017HN/N1 from NXP Semiconductors is an integrated Ku-band downconverter IC for satellite LNB systems, combining pre-amplifier, mixer, buffer amplifier, and PLL synthesizer in a single DHVQFN16 package. It operates across 10.7–12.75 GHz RF input, delivers 42 dB typical conversion gain, 7 dB SSB noise figure, and supports dual LO frequencies (9.75 GHz / 10.6 GHz) for DVB-S/S2 digital satellite reception.
For engineers reviewing the TFF1017HN/N1 datasheet, TFF1017HN/N1 pinout, TFF1017HN/N1 application, or TFF1017HN/N1 equivalent, this device is selected for low-phase-noise, alignment-free LNB designs requiring stable 5 V operation, 25 MHz crystal reference, and minimal external components in compact PCB layouts.
Technical Context
The TFF1017HN/N1 integrates a fully self-contained PLL-based local oscillator with on-chip VCO, PFD, charge pump, and divider, enabling precise 9.75 GHz or 10.6 GHz LO generation from a 25 MHz crystal. Its RF front-end includes matched 50 Ω input impedance and internal biasing for direct connection to pHEMT LNAs.
Conversion occurs within a single monolithic die featuring optimized IF output at 950–2150 MHz into 75 Ω coaxial interface, with integrated loop filter support via LF/VREG pins and HB-controlled band switching. The device uses an exposed thermal pad for junction-to-case thermal resistance of 35 K/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar satellite LNB downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX21002ETX+T | Higher supply current (75 mA), wider IF output (40–2200 MHz), but no integrated crystal oscillator | Requires external 100 MHz reference and frequency divider; less suited for cost-sensitive consumer LNBs | Preferred when ultra-low phase noise (<0.8° RMS) and wide IF bandwidth are prioritized over BOM simplicity |

FAQ
What is the primary function of the TFF1017HN/N1 in a satellite LNB system?
The TFF1017HN/N1 serves as a fully integrated Ku-band downconverter IC that performs RF-to-IF conversion, LO synthesis via PLL, and signal buffering in a single device. It accepts 10.7–12.75 GHz satellite signals and outputs 950–2150 MHz IF signals compatible with DVB-S/S2 receivers. Its architecture eliminates discrete mixers, VCOs, and loop filters, making it central to compact, alignment-free LNB designs.
How does the HB pin control band selection in the TFF1017HN/N1?
The HB (High Band) pin on the TFF1017HN/N1 is a logic-controlled input that selects between two LO frequencies: a low logic level (≤0.8 V) configures the device for 9.75 GHz LO operation (10.7–11.7 GHz RF input), while a high logic level (≥2.0 V) selects 10.6 GHz LO (11.7–12.75 GHz RF input). This enables seamless switching between Ku-band low and high segments without external hardware changes.
What crystal specifications are required for proper operation of the TFF1017HN/N1?
The TFF1017HN/N1 requires a 25 MHz fundamental-mode crystal with 10 pF load capacitance and ≤40 Ω equivalent series resistance (ESR). The crystal connects between XO1 (pin 12) and XO2 (pin 11). NXP specifies no frequency tolerance requirement, confirming compatibility with standard low-cost 25 MHz crystals commonly used in consumer satellite equipment.
Can the TFF1017HN/N1 operate from a supply voltage other than 5 V?
The TFF1017HN/N1 is specified for operation from 4.5 V to 5.5 V, with typical performance characterized at 5 V. While it functions across this range, key parameters-including conversion gain, noise figure, and phase noise-are guaranteed only within the recommended operating conditions. Operation below 4.5 V risks degraded RF performance or failure to lock the PLL; above 5.5 V exceeds absolute maximum ratings and may cause permanent damage.
What thermal considerations apply to the TFF1017HN/N1 in sealed LNB housings?
The TFF1017HN/N1 features an exposed die pad with a typical junction-to-case thermal resistance of 35 K/W. In sealed LNB enclosures, thermal design must ensure the case temperature remains ≤+85 °C under worst-case ambient (+85 °C) and power dissipation (5 V × 52 mA = 260 mW). Recommended practices include soldering the exposed pad to a large copper area and using thermally conductive potting compound to transfer heat to the metal housing.
