What are the key features of LNBH30QTR?
- Integrated step-up DC/DC converter with PWM control delivers stable 13 V and 18 V LNB supply rails from 10 V to 17.5 V input
- I2C interface enables direct microcontroller control of polarization voltage and 22 kHz tone generation
- Compact 16-pin QFN package minimizes PCB footprint in space-constrained satellite receiver designs
What is LNBH30QTR used for?
The LNBH30QTR is designed for satellite set-top boxes, integrated receiver decoders (IRDs), and cable TV headend equipment requiring precise LNB supply voltages of 13 V and 18 V for polarization control. Its I2C interface integrates directly with application processors in smart TV tuner modules and DVB-S2 receiver platforms. The device also suits DiSEqC-compatible satellite dish controllers where tone generation and supply switching must be managed via a 2-wire bus.

Frequently Asked Questions
What input voltage range does the LNBH30QTR support and what output voltages does it provide for LNB polarization?
The LNBH30QTR accepts an input voltage from 10 V to 17.5 V (nominal 12 V) and generates the standard LNB polarization supply voltages of 13 V for vertical polarization and 18 V for horizontal polarization. Its internal step-up converter ensures these regulated outputs remain stable across the full input range, enabling reliable polarization switching in satellite receiver systems.
How does the I2C interface on the LNBH30QTR simplify integration in DVB-S2 satellite receiver designs?
The I2C interface allows a host MCU or SoC to configure the LNBH30QTR's output voltage, enable or disable the 22 kHz DiSEqC tone, and monitor fault conditions over a standard 2-wire bus without dedicated GPIO lines. This reduces routing complexity in DVB-S2 tuner boards, lowers BOM component count, and enables software-controlled LNB management in smart set-top box and integrated receiver decoder platforms.
What package does the LNBH30QTR use and how does its footprint benefit compact satellite tuner PCB layouts?
The LNBH30QTR is housed in a 16-pin QFN (Quad Flat No-Lead) package with the JESD-30 code S-XQCC-N16, offering a very compact PCB footprint suitable for modern miniaturized satellite tuner modules. The exposed pad on the bottom aids thermal dissipation during continuous LNB supply operation, helping maintain reliable performance in densely populated boards inside thin set-top boxes and integrated TV tuners.
