MIMXRT1052CVL5B Introduction

The TPS62840 joins TI's portfolio of highly integrated low-IQ DC/DC converters, enabling designers to maximize power output in the smallest possible solution size.

From a functional point of view, analog chips can be divided into two categories: Power Management ICs and Signal Chains, which are used for power management in electronic equipment systems and conversion between analog/digital signals.

Stop pins turn off all switches to reduce EMI or ripple and minimize distortion passed to precision signal chains, measurements, sensors or wireless connected components. The mode pin allows continuous conduction mode (also known as forced pulse width modulation mode) to improve ripple or noise performance and reduce the impact on transmission in sensitive RF applications. .

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system. A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity.

The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

The working principle is as shown below. The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp).

Ladder type can be used on single-ended (single-ended/unbalanced) and differential (balanced) signals, while lattice type is more suitable for differential (balanced) signals.
