Product details
Overview
STEVAL-CBL010V1 from STMicroelectronics is an evaluation board implementing the LNBH25 IC for satellite LNB power supply and DiSEqC 2.0 control, featuring integrated 22 kHz tone generation, 8–16 V input operation, 15-level programmable output voltage, and I²C interface. It enables single-supply LNB biasing and command encoding in satellite receiver front-ends.
For engineers reviewing the STEVAL-CBL010V1 datasheet, STEVAL-CBL010V1 pinout, STEVAL-CBL010V1 application, or STEVAL-CBL010V1 equivalent, key selection criteria include DiSEqC 2.0 compliance, 22 kHz tone waveform integrity at no load, selectable current limit via external resistor, and integrated step-up DC-DC converter with 93% efficiency at 0.5 A.
Technical Context
The board implements the LNBH25 IC's full functional chain: a high-efficiency step-up PWM converter (integrated N-MOS) delivers regulated LNB output (13/18 V), while the factory-trimmed 22 kHz oscillator supports TTL- or DiSEqC-encoded tone injection via DSQIN. The I²C interface handles voltage level selection, fault reporting, and LMP mode activation.
LNB short-circuit dynamic protection and overtemperature shutdown are monitored via dedicated I²C diagnostic bits. The low-drop post-regulator ensures stable output under varying load conditions, and the built-in LMP function reduces quiescent dissipation during standby.

FAQ
What is the primary function of the STEVAL-CBL010V1 evaluation board?
The STEVAL-CBL010V1 implements the LNBH25 IC to provide regulated 13/18 V power and DiSEqC 2.0-compliant control signals to satellite LNBs. It integrates a step-up DC-DC converter, 22 kHz tone generator, I²C interface, and fault diagnostics-enabling rapid validation of LNB supply architectures in satellite receiver designs.
Does the board support both 13 V and 18 V LNB output modes?
Yes. The board supports 15 programmable output voltage levels, covering standard 13 V (horizontal polarization) and 18 V (vertical polarization) LNB bias requirements. Voltage selection is controlled via I²C commands, and the output is stabilized by an integrated low-drop post-regulator.
Can the 22 kHz tone be generated without loading the LNB?
Yes. The LNBH25's 22 kHz oscillator maintains waveform integrity even at no load, as verified in the data brief. This ensures reliable tone detection by LNBs during initialization or low-current standby states, eliminating false triggering or synchronization loss.
How is overcurrent protection implemented on this board?
Overcurrent protection is implemented via an external resistor (RSEL) that sets the current limit threshold. The LNBH25 also provides dynamic short-circuit protection and reports fault status-including overload and overtemperature events-through dedicated I²C diagnostic bits for real-time system monitoring.
