Product details
Overview
STEVAL-CBL015V1 from STMicroelectronics is an evaluation board implementing the LNBH29 IC for single-LNB power supply and DiSEqC 1.x control in satellite TV reception systems. It delivers regulated 13/18 V output, integrates a factory-trimmed 22 kHz tone generator, supports I²C interface and DSQIN-based DiSEqC encoding, and operates from 8–17.5 V input with up to 0.5 A output current.
For engineers reviewing the STEVAL-CBL015V1 datasheet, STEVAL-CBL015V1 pinout, STEVAL-CBL015V1 application, or STEVAL-CBL015V1 equivalent, key selection considerations include DiSEqC 1.x compliance, integrated step-up DC-DC efficiency (93% @ 0.5 A), programmable output voltage levels (6), 22 kHz tone waveform integrity at no load, and LNB short-circuit dynamic protection.
Technical Context
The board implements the LNBH29 IC's full functional chain: a high-efficiency step-up PWM converter with integrated N-MOSFET, low-drop post-regulator, and dual-mode output (13 V/18 V) selectable via I²C or DSQIN. The 22 kHz tone generator is factory-trimmed and maintains waveform fidelity across load conditions.
DiSEqC 1.x data encoding is performed through TTL-compatible DSQIN pin control, while I²C enables full configuration of output voltage level (6 presets), current limit (via external resistor), and diagnostic readback of overload/overtemperature status bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 17.5 V - Enables direct use with standard satellite receiver power supplies without pre-regulation. |
| Output Voltage Levels | 6 programmable levels (13 V / 18 V main modes) - Matches international LNB bias requirements for polarity selection and band switching. |
| 22 kHz Tone Accuracy | Factory-trimmed ±0.5% - Ensures reliable DiSEqC command recognition by LNBs without external filtering or calibration. |
| DC-DC Efficiency | 93% @ 0.5 A load - Minimizes thermal stress and enables compact heatsink-free PCB layout in set-top box designs. |
| Short-Circuit Protection | Dynamic response < 1 µs - Prevents LNB damage during antenna cable faults or connector shorts without latch-off. |
| I²C Diagnostic Bits | Overload, overtemperature, and fault status flags - Enables real-time system-level health monitoring without additional sensors. |

FAQ
What is the primary function of the STEVAL-CBL015V1 evaluation board?
The STEVAL-CBL015V1 is a fully assembled evaluation board that demonstrates the LNBH29 IC's capability to supply and control a single satellite LNB. It provides regulated 13/18 V bias, generates a precise 22 kHz tone, and supports DiSEqC 1.x communication via DSQIN or I²C-enabling rapid validation of LNB interface designs in DVB-S/S2 receivers.
Does STEVAL-CBL015V1 support both voltage mode and tone mode LNB control?
Yes. The board supports dual-mode LNB control: output voltage selection between 13 V (vertical) and 18 V (horizontal) via I²C or DSQIN, and simultaneous 22 kHz tone injection for band switching. The tone generator is factory-trimmed and maintains waveform integrity even under no-load conditions, meeting ETSI EN 300 468 requirements.
Can the output current limit be adjusted on this board?
Yes. The LNBH29 IC on STEVAL-CBL015V1 allows selectable output current limit via an external resistor connected to the ILIM pin. This enables design-specific tailoring of short-circuit protection threshold-e.g., 0.45 A, 0.5 A, or 0.6 A-without firmware changes or hardware redesign.
Is STEVAL-CBL015V1 RoHS compliant and suitable for production use?
Yes. The board and its LNBH29 IC are RoHS compliant (per DocID025829 Rev 1). While intended as an evaluation tool, its reference design-including QFN16 layout, thermal pad grounding, and input/output filtering-is production-ready and used as the basis for many commercial satellite receiver power stages.
