Product details
Overview
STEVAL-CBL007V1 from STMicroelectronics is a DiSEqC 1.X-compliant LNB power supply demonstration board built around the LNBH23L IC, providing complete interface and DC-DC conversion for satellite low-noise block downconverters. It operates from a single 8–15 V input, delivers up to 0.5 A output with 93% typical efficiency, includes 22 kHz tone generation, and supports I²C-controlled voltage/current configuration in satellite receiver front-end designs.
For engineers reviewing the STEVAL-CBL007V1 datasheet, STEVAL-CBL007V1 pinout, STEVAL-CBL007V1 application, or STEVAL-CBL007V1 equivalent, this board serves as a validated reference for LNB power delivery, DiSEqC 1.X command encoding, auxiliary modulation, and thermal/short-circuit protection implementation in satellite set-top box and multiswitch systems.
Technical Context
The board implements the LNBH23L's integrated step-up PWM controller with internal NMOS switch and low-drop post-regulator, enabling stable 13/18 V LNB supply under dynamic load. Its I²C interface allows real-time monitoring of overload and over-temperature status via diagnostic bits, while the EXTM pin accepts external modulation signals for DiSEqC 1.X frame encoding.
It integrates a precision 22 kHz tone generator compliant with ETSI EN 300 421 and EN 301 790 standards, and uses an external resistor to set current limit - supporting configurable protection thresholds across diverse LNB loads without firmware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 8 V to 15 V DC - enables direct use with standard satellite receiver power rails without pre-regulation. |
| Output Voltage Options | 13 V or 18 V selectable via I²C - matches universal LNB polarity requirements (vertical/horizontal) in DVB-S/S2 systems. |
| Max Output Current | 0.5 A - sufficient for driving dual-output LNBs and legacy single-LNB modules. |
| DC-DC Efficiency | 93% typical at 0.5 A - minimizes heat rise and improves thermal margin in enclosed set-top enclosures. |
| 22 kHz Tone Accuracy | ±0.5% frequency tolerance - ensures reliable DiSEqC command recognition by satellite LNBs per ETSI standards. |
| Protection Features | Internal overload, over-temperature, and dynamic short-circuit detection with I²C flag reporting - eliminates need for external fault-sensing circuitry. |

FAQ
Is STEVAL-CBL007V1 still in active production?
No. STEVAL-CBL007V1 is marked as obsolete per STMicroelectronics' official documentation (Doc ID 17669 Rev 1, August 2010). It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and repair support.
Can STEVAL-CBL007V1 be used with modern DVB-S2X receivers?
Yes - its LNBH23L-based architecture fully supports DiSEqC 1.X protocols used by all DVB-S, S2, and S2X receivers. The 13/18 V switching, 22 kHz tone, and EXTM modulation interface are functionally identical to current-generation implementations.
What external components are required to operate the board?
Only a DC input source (8–15 V), I²C host controller (e.g., microcontroller), and optional external current-limit resistor. All critical passives, power MOSFET, and regulation circuitry are integrated on the board - no additional LNB interface components are needed.
Does the board provide ESD or surge protection for LNB lines?
No. STEVAL-CBL007V1 implements functional LNB power delivery and DiSEqC signaling but does not include TVS diodes or gas discharge tubes for lightning/surge suppression. External protection must be added per system-level EMC and safety requirements.
