The LMH2180SDE/NOPB is a multifunctional device from Texas Instruments. It is a single-in-line (SIL) package chip that combines a selectable clock buffer with a programmable delay line. The device has built-in low jitter, constant propagation delay, low power, and simple programming for a wide range of applications, making it one of the most versatile clock buffers in the market. The main features of the LMH2180SDE/NOPB are its use as a clock buffer, giving it the flexibility to amplify either a single-ended input clock or two differential-input clocks. It is also designed to reduce jitter while also making it easy to program the output frequency. This makes the device ideal for clock buffering applications such as those used in the clock synchronization of multiple data and clock lines.The device also features a programmable delay line, which can be used to adjust the propagation delay between two different clocks. This is useful in situations where two different clocks must be synchronized without significantly changing the frequency or duty cycle of either clock. The device is also capable of providing an adjustable delay ranging from 0.1ns to 15ns, making it a great device for communicating between backplanes, networking systems, and multiple interconnecting protocols.In terms of its working principle, the LMH2180SDE/NOPB has two main components. The first is an output buffer that provides one or two clock outputs with adjustable gain and high-impedance inputs. The second component is a programmable delay line that allows for different propagation delays between the two clocks. It can be programmed using an on-chip voltage-controlled oscillator (VCO), allowing for the frequency and phase of the output clocks to be controlled independently.In applications where clock synchronization is required, the LMH2180SDE/NOPB allows for easy synchronization of clocks between different data and clock lines. The device also has low power consumption and low jitter, making it an excellent choice for low-power clocking applications. Additionally, the device has a wide range of adjustable delays, making it a great choice for creating networks with multiple protocols and connecting different backplanes.Overall, the LMH2180SDE/NOPB is a versatile chip that combines the functionality of a clock buffer and programmable delay line into one single-in-line package. It is versatile enough to be used for both clock buffering and synchronization applications, making it an excellent choice for low-power clocking solutions. Additionally, its low power consumption, low jitter, and wide range of adjustable delays make it a great choice for many applications.
