Product details
Overview
STEVAL-LNBH06 from STMicroelectronics is an evaluation board for powering satellite low-noise block downconverters (LNBs), built around the LNBH26S IC. It provides I²C-controlled 12 V DC-DC conversion, programmable 15-level output voltage (13–21 V), integrated 22 kHz tone generation compliant with DiSEqC™ standards, and dual-channel operation for twin-tuner satellite receivers.
For engineers reviewing the STEVAL-LNBH06 datasheet, STEVAL-LNBH06 pinout, STEVAL-LNBH06 application, or STEVAL-LNBH06 equivalent, key selection criteria include dual LNB channel support, I²C-configurable voltage/tone control, ±4 kV ESD tolerance on power outputs, LPM mode for thermal management, and built-in short-circuit/dynamic overload protection.
Technical Context
The board implements a fully integrated step-up PWM DC-DC converter with internal N-MOSFET, operating from 8–16 V input to deliver up to 0.5 A per channel at >93% typical efficiency. It embeds factory-trimmed 22 kHz tone generation with waveform integrity maintained even at no load.
I²C interface enables real-time monitoring of fault conditions (overload, overtemperature) via diagnostic bits, while DSQIN pins accept TTL-level DiSEqC™ envelope signals for immediate data encoding. Dual independent channels support simultaneous operation with separate VOUT-A/VOUT-B, BPSW-A/B, and DETIN-A/B terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 16 V - supports wide-range DC supply common in satellite receiver front-ends |
| Output Voltage Programmability | 15 levels (13–21 V) - meets regional LNB voltage specs without external DAC or trimmer |
| 22 kHz Tone Accuracy | Factory-trimmed ±1% - ensures reliable DiSEqC™ command recognition across receiver brands |
| Efficiency (typ.) | 93% @ 0.5 A - minimizes thermal stress in enclosed dish-mounted enclosures |
| ESD Tolerance | ±4 kV HBM on LNBOUT pins - protects against static discharge during antenna installation/maintenance |
| Protection Features | Overload, overtemperature, short-circuit dynamic protection - enables robust field deployment without external supervision |

FAQ
What is the primary function of the STEVAL-LNBH06 evaluation board?
The STEVAL-LNBH06 is a complete reference design for powering satellite LNBs using the LNBH26S IC. It delivers regulated DC output (13–21 V) with integrated 22 kHz tone generation and DiSEqC™ envelope support, enabling dual-channel operation for twin-tuner satellite receivers without external signal conditioning.
Does the board support both single and dual LNB configurations?
Yes - the STEVAL-LNBH06 implements two fully independent LNB power channels (A and B), each with dedicated VOUT, BPSW, DETIN, and DSQOUT pins. This allows simultaneous powering and control of two LNBs, essential for modern dual-tuner satellite receivers and multi-feed dish systems.
How is output voltage programmed on the STEVAL-LNBH06?
Voltage is set via I²C commands to the onboard LNBH26S, selecting one of 15 factory-calibrated levels between 13 V and 21 V. No external resistors or DACs are required - configuration is software-defined and compatible with standard satellite receiver firmware stacks.
Can the 22 kHz tone be disabled or gated independently per channel?
No - the 22 kHz tone generator is shared and globally enabled/disabled via the TONE_EN bit in the LNBH26S register map. However, channel-specific DiSEqC™ envelope modulation is supported through separate DSQIN-A/DSQIN-B inputs, allowing independent command transmission per LNB path.
