Product details
Overview
STEVAL-CBL005V1 from STMicroelectronics is an LNB power supply demonstration board based on the LNBH23 IC, designed to deliver regulated 13/18 V and 22 kHz tone generation for satellite TV low-noise block downconverters. It operates from a single 8–15 V input, integrates a step-up DC-DC converter, I²C control interface, and factory-trimmed 22 kHz tone generator compliant with DiSEqC™ standards.
For engineers reviewing the STEVAL-CBL005V1 datasheet, STEVAL-CBL005V1 pinout, STEVAL-CBL005V1 application, or STEVAL-CBL005V1 equivalent, this board enables rapid validation of LNB power delivery, DiSEqC™ command encoding, voltage switching (13 V/18 V), and real-time diagnostics in satellite receiver front-end designs.
Technical Context
The board implements the LNBH23 - a monolithic LNB supply and control IC - in QFN32 package, integrating a current-mode step-up DC-DC controller, I²C-compatible logic, DSQIN/TTL-level DiSEqC™ encoder input, and factory-calibrated 22 kHz oscillator. Output voltage selection (13 V or 18 V) is controlled via I²C register writes or external VCTRL pin.
It supports dual-mode operation: standalone mode using DSQIN for DiSEqC™ burst encoding, and I²C-managed mode for full register access, fault reporting (overcurrent, overtemperature), and dynamic voltage/tone control. The LX switch node drives an external 22 µH inductor and 100 µF output capacitor for stable LNB biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 15 V DC - enables direct use with common 12 V industrial/satcom power rails without pre-regulation. |
| Output Voltage Options | 13 V or 18 V selectable - matches standard LNB vertical/horizontal polarization requirements per EN 50494. |
| 22 kHz Tone Accuracy | Factory-trimmed ±0.5% - ensures reliable DiSEqC™ command recognition by satellite multiswitches and LNBs. |
| I²C Interface | Standard-mode (100 kHz) - allows host MCU integration for remote diagnostics, voltage switching, and fault logging. |
| Max Output Current | 750 mA - sufficient to power dual-output LNBs or multi-LNB distribution systems with margin. |
| DSQIN Pin Logic | TTL-compatible (0–5 V) - permits direct connection to microcontroller GPIO for DiSEqC™ burst generation without level-shifting. |

FAQ
What is the primary function of the STEVAL-CBL005V1 board?
The STEVAL-CBL005V1 is a demonstration board that implements the LNBH23 IC to provide regulated 13/18 V DC power and a precise 22 kHz tone signal to satellite LNBs. It validates full LNB supply and DiSEqC™ control functionality, including I²C programmability, voltage switching, and fault monitoring - all in a single PCB layout with documented schematics and BOM.
Does the board support both I²C and TTL-based DiSEqC™ control?
Yes. The board supports dual control modes: I²C register access for full configuration and diagnostics, and TTL-level DSQIN pin operation for direct DiSEqC™ burst encoding. The DSQIN pin accepts 0–5 V logic signals and triggers internal tone generation synchronized to the factory-trimmed 22 kHz oscillator, enabling immediate DiSEqC™ command transmission without host processor intervention.
Can the output voltage be changed dynamically during operation?
Yes. Output voltage (13 V or 18 V) can be switched dynamically via I²C register write to the VSEL bit or by applying a logic-high or logic-low level to the VCTRL pin. This allows real-time polarization selection in satellite receivers - for example, toggling between vertical (13 V) and horizontal (18 V) LNB biasing during channel changes - with no power cycle required.
Is external firmware or software required to operate the board?
The board includes the "LNBxxx Control Suite" Windows GUI software for immediate I²C configuration, voltage/tone control, and diagnostic readback. However, no firmware is embedded on the board itself - it functions as a passive hardware platform. All control is executed by the host PC or MCU communicating over the onboard I²C interface; the GUI is optional for evaluation, not mandatory for basic operation.
