The demonstration board STEVAL-CBL006V1 implements a DC-DC converter based on the device LNBH24. It gives good performance in a simple and cheap way and minimum external components are required. It includes all the functions that allow the design of a dual tuner STBs with supplying/interfacing function in accordance with the international standards. It also includes an I²C bus interface and, thanks to a fully integrated step-up DC-DC converter, it works with a single input voltage supply in the range of 8 V to 15 V.

The STEVAL-CBL007V1 demonstration board is intended to provide information and suggestions on the correct use of the LNBH23L device.

The LNBH23L is an integrated solution for supplying/interfacing satellite LNB modules. Simple and inexpensive, it provides good performance while minimizing the number of external components required.

It includes all functions needed for LNB supply and interfacing, and is compliant with international standards. It includes an I²C bus interface and, due to the fully integrated step-up DC-DC converter, functions with a single input voltage supply from 8 V to 15 V.

The STEVAL-CBP005V1 demonstration board functions as a front panel solution for the HR21 set-top box (STB), and is designed to allow testing of the versatile LED controller/driver STLED316S.

The HR21 main board serves as the host (master), and the STEVAL-CBP005V1 demonstration board functions as a slave. The interface is an 11-pin connector cable, which provides all required device control signals, the 3.3 and 5 V supply, the reset and IR sensor data lines, and ground. The board also provides all necessary function switches as well as LEDs for function/status indication.

The STEVAL-CBP005V1 demonstration board must be connected to the host to function properly. Factory testing was completed using a test jig, which emulated the host.

The STEVAL-CBP006V1 UniPower demonstration board is designed to provide a ready-to-use platform for power supply management and user-interface control developed around the STM8S MCU. The board can manage various wakeup sources, and perform power supply switching of the rest of the application during standby. The board also features an ST capacitive touch-sensing software library capable of turning any 8-bit STM8 microcontroller into a capacitive touch-sensing controller.

The UniPower demonstration board is preprogrammed with demonstration firmware to manage most of the system’s hardware resources, such as digital and analog I/Os, LEDs and mechanical buttons. Touch-sensing functions can thus be easily combined with traditional MCU capabilities by selecting appropriate modules from the UniPower MCU firmware library. The UniPower demonstration board allows designers who are familiar with the use of standard microcontrollers to perform extensive application standby power management and create higher-end look-and-feel human interfaces by replacing conventional electromechanical switches with capacitive touchkeys. The application cost can be reduced by choosing a smaller MCU from the STM8S portfolio. The board is delivered with a SWIM interface, allowing adaptation of the firmware to application requirements. This simplifies the concept of the UniPower MCU firmware library, and makes the evaluation of the key features for end-applications easy. Maturity, robustness, flexibility and performance make this solution simple to implement and quick to market. It can be integrated into various types of consumer application, such as set-top boxes, digital TVs and home appliances. For further details about the touch-sensing software library, please refer to the STM8 touch-sensing firmware documentation.

This demonstration board is designed to evaluate the TSH345, a single supply triple video buffer featuring an internal gain of 6 dB and an internal low pass filter of 36 MHz cut-off frequency for each channel to fit with high definition requirements for video line interfaces.

This demonstration board is designed to evaluate the TSH346, a single supply triple video buffer featuring an internal gain of 6 dB and an internal low pass filter of 36 MHz cut-off frequency for each channel to fit with high definition requirements for video line interfaces.

The STEVAL-CCA018V1 demonstration board is designed provide a platform for evaluating the performance of the TS4657 stereo digital-to analog-converter (DAC). The TS4657 integrates a high-performance audio line driver capable of generating a 2.2 V_RMS output level from a single 3.0 to 5.5 V supply.

A single supply is sufficient for the digital and analog parts of the circuit, eliminating the need for external regulators.

The TS4657 is a low consumption device, with only 22 mW of power dissipation at 3.0 V power supply during full operation.

A 16-bit multi-bit sigma-delta DAC is used, operating at 256xFs with over sampling digital interpolation filters.

The digital audio data can be 16 to 24-bits long and sample rates from 32 to 48 kHz are supported.

The output stage signal is ground-referenced by using an internal self-generated negative power supply, so bulky external output coupling capacitors are not necessary.

The STEVAL-CCA022V1 demonstration board is designed to help characterize single operational amplifiers in SOT23-5 (two different pinouts) and SC70-5 packages.

Operational amplifiers in SOT23-6 and SC70-6 packages can also be characterized but their standby pin is not usable because it is connected to V_CC + on the board.

The STEVAL-CCA022V1 allows to characterize, among the others, the following op-amps (not included in the package): TS507, TSV621, TSV631, TSV911, TSV991, TS1851, TS1871, TS931, TS941, TS951, TS971, TS321.

The STEVAL-CCA023V1 demonstration board is designed as an evaluation platform for the TS472 low noise microphone preamplifier with 2.0 V bias and active low standby mode.

The board supports customization of the testing conditions, allowing the gain of the TS472 device to be adjusted, or an electret microphone to be biased either externally or using the TS472 builtin 2.0 V bias voltage.

The STEVAL-CCH002V2 demonstrates the functions and performance of STMicroelectronics’ STHDMI002A, STDVE103A, STDVE001A, STMAV340, and STHDMI002A digital switches/equalizers, and STMAV335 and STMAV340 analog switches.

The purpose of the board is to demonstrate the capabilities of ST's video switches and buffers (while providing an example of the appropriate use of signal line protection devices in all I/O lines) for both standard analog or high-speed TMDS (transition minimized differential signaling) digital signals.

The board consists of several input/output connectors and supports VGA (RGB), Y Pb Pr (component video), DVI-I analog, CVBS (composite video) and S-video analog formats, as well as HDMI and DVI-I digital formats.

Demonstration of the various devices is achieved by setting the appropriate jumpers on the demonstration board.

Also included is a 2-line backlit LCD with16 characters-per-line, which displays the selection status as well as the control signals sensed by the preprogrammed microcontroller.
