The LMH2191TMX/NOPB is a new type of clock buffers, drivers, and high-frequency components developed by Texas Instruments for industrial applications. Its feature set and variability make it ideal for use in a variety of industrial applications, from utility meters to medical instruments.

The fundamental application field for this buffer is in the separate control of multiple clock domains and eventually in the distribution of clock signals. This device is able to act as a bidirectional static bus switch, providing isolation and synchronization between domains. Meanwhile, it has the ability to double the driving current going to the output domain and thus provide a more stable signal.

On the silicon hardware level, LMH2191TMX/NOPB is utilizing a popular architecture called voltage-mode logic. Such a logic works by using varying voltages instead of logic state. This provides for easier design as the logic can be configured to dynamically adjust itself depending on specific external conditions.

The core of the LMH2191TMX/NOPB is a differential bus switch that can switch up to eight input/output pairs. This is a popular architecture for clock distribution in wideband applications thanks to its ability to operate uninterrupted and over a wide temperature range. The differential bus switch is based on the more traditional master-slave synchronization logic, allowing for fast and reliable bidirectional communication between two clock domains.

The device is also equipped with a slew rate control system that has been optimized to stabilize the output signal and reduce propagation delay in each clock domain, resulting in better reliability and accuracy.

Furthermore, the LMH2191TMX/NOPB features several power-saving features, including on-chip ESD protection, a low-power Sleep Mode, and the ability to reduce power consumption below 70 mW during periods of non-active usage. These features make the LMH2191TMX/NOPB a reliable and energy-efficient solution for a wide variety of industrial applications.

The LMH2191TMX/NOPB is a revolutionary clock buffer designed to provide stable and reliable clock synchronization between different circuits. Its voltage-mode logic, differential bus switch, and low-power sleep mode make it suitable for a range of industrial applications, from medical devices to utility meters.
