NXP Semiconductors TFF1007HN/N1,118

Overview

TFF1007HN/N1,118 from NXP Semiconductors is a Ka-band frequency synthesizer IC designed as a low-phase-noise local oscillator generator for VSAT upconverters. It delivers 14.62–15.00 GHz RF output with −109 dBc/Hz typical phase noise at 100 kHz offset (IESS-308 compliant), −4 dBm minimum output power, and operates from a 3.3 V supply drawing 116–130 mA. Its primary system role is closed-loop LO signal generation in satellite terminal transmit chains.

For engineers reviewing the TFF1007HN/N1,118 datasheet, TFF1007HN/N1,118 pinout, TFF1007HN/N1,118 application, or TFF1007HN/N1,118 equivalent, this page provides verified functional context, validated HVQFN24 pin mapping, confirmed IESS-308 compliance, and real-world design implications of its third/fourth-order PLL architecture, differential RF outputs, and divider-controlled synthesis.

Technical Context

The TFF1007HN/N1,118 integrates a voltage-controlled oscillator (VCO) with 0.75 GHz/V tuning sensitivity, a phase-frequency detector (PFD) and charge pump (2 mA typical), and a programmable divider (64 default, also supports 16/32/128/256). Its loop filter interface supports both type-2 and type-3 configurations via CPOUT and VTUNE pins, enabling optimized spurious suppression and stability.

It features dual differential RF output buffers (BUF1_P/N, BUF2_P/N) with 50 Ω collector impedances, internally regulated VCO reference voltage (2.5–2.9 V on VREGVCO), and a CMOS-compatible lock detect (LCKDET) with 7–93% hysteresis window referenced to VREGVCO. Reference input is fully differential (IN(REF)_P/N), supporting 228.44–234.38 MHz AC-coupled signals.

FAQ

What is the guaranteed RF output frequency range for the TFF1007HN/N1,118?

The TFF1007HN/N1,118 guarantees an RF output frequency range of 14.62 GHz to 15.00 GHz in locked state, as specified in Table 10 of the official NXP datasheet (Rev. 1, 2012). This range is achieved with the default divider setting of 64 and a reference input of 228.44–234.38 MHz. Operation outside this band is not characterized or supported.

Does the TFF1007HN/N1,118 meet IESS-308 phase noise requirements?

Yes, the TFF1007HN/N1,118 is explicitly designed and tested to comply with IESS-308 from Intelsat. Its typical synthesizer phase noise is −109 dBc/Hz at 100 kHz offset (with divider = 64, loop bandwidth = 2 MHz, and reference phase noise = −150 dBc/Hz), satisfying the standard's spectral purity requirements for Ka-band VSAT transmitters.

Can the TFF1007HN/N1,118 operate with a single-ended reference input?

Yes, the TFF1007HN/N1,118 supports single-ended reference input via IN(REF)_P (pin 9), provided IN(REF)_N (pin 10) is terminated with the same impedance as the driving source (e.g., 50 Ω to ground), as shown in Figure 8 of the datasheet. AC coupling remains mandatory for both configurations.

What is the function of the VREGVCO pin on the TFF1007HN/N1,118?

VREGVCO (pin 1) provides a stabilized 2.5–2.9 V output that serves as the reference voltage for the VCO tuning circuit. The loop filter must be connected to this pin-not to the main supply-to ensure tuning voltage stability against supply ripple, which directly impacts phase noise performance in the TFF1007HN/N1,118.

Is the TFF1007HN/N1,118 pin-compatible with other NXP frequency generators?

No, the TFF1007HN/N1,118 uses a unique 24-pin HVQFN24 (SOT616-1) pinout optimized for Ka-band LO synthesis. It is not pin-compatible with other NXP RF synthesizers such as the TFFM003 or ATECC series, which differ in function, frequency range, and pin assignment-even when sharing the same package footprint.
