Product details
Overview
STEVAL-CBL013V1 from STMicroelectronics is an evaluation board for the LNBH25L single LNB supply and control IC, implementing a DiSEqC 1.x-compliant DC-DC converter with integrated 22 kHz tone generation, 8-level programmable output voltage (13/18 V), 0.5 A current capability, and 93% typical efficiency at full load. It enables satellite TV receiver front-end power and control in single-tuner configurations.
For engineers reviewing the STEVAL-CBL013V1 datasheet, STEVAL-CBL013V1 pinout, STEVAL-CBL013V1 application, or STEVAL-CBL013V1 equivalent, key selection considerations include DiSEqC 1.x compliance, I²C-controlled LNB voltage/tone sequencing, single 8–16 V input operation, and built-in short-circuit and thermal protection diagnostics.
Technical Context
The board implements the LNBH25L IC's high-efficiency step-up PWM converter with integrated N-MOSFET and low-drop post-regulator, supporting 8 V to 16 V input while delivering regulated 13 V or 18 V LNB supply. Its factory-trimmed 22 kHz tone generator maintains waveform integrity under no-load and loaded conditions per EN 50494.
I²C interface enables real-time configuration of output voltage level, current limit (via external resistor), and DiSEqC command decoding via DSQIN (TTL-compatible). Internal protection includes overload detection, overtemperature shutdown, and dynamic short-circuit response reported via I²C status bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 16 V DC - supports wide-range satellite receiver power supplies without external regulation |
| Output Voltage Levels | 8 programmable levels (13 V / 18 V) - matches standard LNB polarity and band selection requirements |
| Max Output Current | 0.5 A - sufficient for single-LNB operation including startup surge and DiSEqC burst loading |
| 22 kHz Tone Accuracy | Factory-trimmed ±0.5% - ensures reliable DiSEqC 1.x command recognition across receivers |
| DC-DC Efficiency | 93% typ. @ 0.5 A - minimizes thermal stress and enables compact enclosure design |
| Protection Features | Overload, overtemperature, and dynamic short-circuit - provides fault-safe LNB interface with I²C-readable status |

FAQ
What is the primary function of the STEVAL-CBL013V1 evaluation board?
The STEVAL-CBL013V1 is a fully assembled evaluation board for the LNBH25L IC, designed to demonstrate and validate single-LNB power supply and DiSEqC 1.x control functionality-including programmable 13/18 V output, 22 kHz tone generation, and I²C-based configuration-within satellite TV receiver front-end designs.
Does STEVAL-CBL013V1 support DiSEqC 2.x or higher protocols?
No. The board implements only DiSEqC 1.x compliance as defined by the underlying LNBH25L IC. It does not support DiSEqC 2.x features such as bidirectional communication, enhanced error checking, or extended command sets. Protocol extension requires hardware redesign and firmware-level changes beyond this evaluation platform.
Can the output current limit be adjusted without changing external components?
No. The output current limit is set by an external resistor connected to the ILIM pin of the LNBH25L IC on the board. No onboard digital trimming or I²C-adjustable current limit is implemented-adjustment requires physical resistor replacement per the LNBH25L datasheet's ILIM calculation formula.
Is the 22 kHz tone generator active during all output voltage states?
Yes. The 22 kHz tone generator remains functional and maintains waveform integrity across all eight programmable output voltage levels (including 13 V and 18 V), both under load and no-load conditions, as verified in the LNBH25L data brief and confirmed by factory trimming.
