STMicroelectronics STEVAL-CBL016V1

Overview

STEVAL-CBL016V1 from STMicroelectronics is an evaluation board implementing the LNBH29 IC for single-LNB satellite receiver power and control, supporting DiSEqC 1.X protocol, 22 kHz tone generation, 6-level programmable output voltage (13/18 V), and EXTM analog modulation input. It operates from 8–17.5 V input with integrated step-up DC-DC converter and delivers up to 0.5 A at >93% efficiency.

For engineers reviewing the STEVAL-CBL016V1 datasheet, STEVAL-CBL016V1 pinout, STEVAL-CBL016V1 application, or STEVAL-CBL016V1 equivalent, key selection considerations include DiSEqC 1.X compliance, EXTM-based tone injection support, I²C-controlled LNB supply voltage selection, and thermal/overcurrent diagnostics via register bits.

Technical Context

The board implements the LNBH29 IC in QFN16 (4×4 mm) package, integrating a high-efficiency PWM step-up converter with internal N-MOSFET, low-drop post-regulator, and precision 22 kHz tone generator. It accepts external 22 kHz tone via EXTM pin and supports I²C-configurable output voltage levels (13 V / 18 V ±5%) and current limit (0.3–0.8 A).

Internal protection includes overtemperature shutdown, overload detection with I²C status flags, and dynamic short-circuit protection during LNB startup/transient events. The design targets cost-sensitive single-tuner satellite receivers requiring stable LNB bias and DiSEqC command compatibility.

FAQ

Does STEVAL-CBL016V1 support DiSEqC 2.0 commands?

No. The board implements the LNBH29 IC, which is explicitly compliant only with DiSEqC 1.X standards per ST's data brief. It lacks hardware support for DiSEqC 2.0 bidirectional communication or enhanced command sets such as positioner control or status reporting.

Can the 22 kHz tone be generated internally without external EXTM signal?

Yes. The LNBH29 on STEVAL-CBL016V1 includes a built-in 22 kHz oscillator; EXTM is optional for synchronized or externally derived tone injection. Internal tone generation meets DiSEqC timing and waveform fidelity requirements without external components.

What is the purpose of the I²C diagnostic bits on this board?

The I²C register provides real-time status bits indicating overtemperature condition, output overload, and LNB short-circuit event. These bits enable host firmware to implement fail-safe shutdown, retry logic, or field-service diagnostics without adding discrete sensing circuitry.

Is STEVAL-CBL016V1 RoHS compliant and lead-free?

Yes. As stated in the official STMicroelectronics data brief (DocID025825 Rev 1), STEVAL-CBL016V1 is RoHS compliant and manufactured using lead-free processes, meeting EU Directive 2011/65/EU requirements for hazardous substances restriction.
