Product details
Overview
STEVAL-CBL003V1 from STMicroelectronics is a demonstration board implementing the LNBH23 IC to supply and control satellite low-noise block downconverters (LNBs) in dish antenna systems. It features an integrated step-up DC-DC converter, 8–15 V single-input operation, factory-trimmed 22 kHz tone generation, I²C interface for diagnostics/control, and DiSEqC™-ready DSQIN pin support.
For engineers reviewing the STEVAL-CBL003V1 datasheet, STEVAL-CBL003V1 pinout, STEVAL-CBL003V1 application, or STEVAL-CBL003V1 equivalent, this board enables rapid validation of LNB power delivery, tone signaling, and I²C-based configuration in satellite receiver front-end designs - especially where compliance with EN 50494/EN 50607 DiSEqC standards is required.
Technical Context
The board implements the LNBH23's full functional chain: input voltage regulation via internal boost converter, precise 22 kHz tone generation (±0.5% factory trim), and dual-mode control (DSQIN TTL-level or I²C command). The LNBH23 integrates all critical analog and logic blocks - including current-sense feedback, overcurrent protection, and DiSEqC™ pulse encoding circuitry - eliminating external timing components.
It operates as a complete LNB bias and control subsystem: delivering regulated 13/18 V output, switching between vertical/horizontal polarization via voltage selection, and embedding 22 kHz tone for band selection - all synchronized to DiSEqC™ message framing without host MCU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 15 V DC - supports wide-range 12 V nominal systems including automotive and portable satellite receivers. |
| LNB Output Voltage | 13 V / 18 V selectable - directly controls LNB polarization (vertical/horizontal) per EN 50494 standard. |
| 22 kHz Tone Accuracy | ±0.5% factory-trimmed - ensures reliable band switching in DVB-S/S2 receivers without external calibration. |
| I²C Interface | Standard-mode (100 kHz) - enables remote diagnostics, fault reporting, and dynamic tone enable/disable from host MCU. |
| DSQIN Pin Function | TTL-compatible DiSEqC™ data input - allows direct connection to microcontroller GPIO for real-time DiSEqC™ burst encoding. |
| Overcurrent Protection | Integrated foldback current limit - prevents damage during LNB short-circuit or cable fault conditions. |

FAQ
What is the primary function of the STEVAL-CBL003V1 board?
The STEVAL-CBL003V1 is a dedicated demonstration board for the LNBH23 IC, designed to validate LNB power delivery and control in satellite TV reception systems. It provides regulated 13/18 V outputs, factory-trimmed 22 kHz tone generation, and DiSEqC™-compatible signaling - all implemented with minimal external components per the LNBH23's integrated architecture.
Does the board support both I²C and DSQIN control simultaneously?
Yes - the board supports concurrent use of I²C for configuration and diagnostics, and DSQIN for real-time DiSEqC™ pulse encoding. The LNBH23 internally prioritizes DSQIN for tone generation during active DiSEqC™ bursts while allowing I²C to monitor status and adjust settings between commands.
Can the 22 kHz tone frequency be adjusted externally?
No - the 22 kHz tone generator is factory-trimmed to ±0.5% accuracy and not user-adjustable. Its frequency is fixed to meet EN 50494 requirements for satellite band selection; tuning is unnecessary and unsupported by the LNBH23 hardware or board design.
Is the STEVAL-CBL003V1 RoHS-compliant and suitable for production use?
The board complies with RoHS Directive 2002/95/EC as confirmed in ST's official documentation. However, it is intended for evaluation and development only - not for end-product integration. For production, designers must implement the LNBH23 in their own PCB layout following ST's layout guidelines and thermal recommendations.
