MC100LVEP14DTR2

Modern electronic devices increasingly require alternative methods for creating and distributing clock signals, to ensure that signals are accurate and meet the bandwidth, noise, power, and timing requirements of the system. Clock Buffers, Drivers and other related circuits provide the necessary method of distributing clock signals and are the building block for creating clock networks. This functionality is provided by MC100LVEP14DTR2, a high-performance, low-phase noise Clock Driver.

Application Field

MC100LVEP14DTR2 offers a slew of features that can help it fit into a large range of applications, such as A/D & D/A Conversion, High-speed Serial Data Links, and Automotive Technologies. This application range can be expanded further by configuring it to provide varying levels of output drive and slew rate. Additionally, it offers a differential output of up to 1.5GHz and a skew-matched output of less than 20ps.

The device is also suitable for Long-reach Applicable, providing a differential output frequency of up to 450MHz and skew matched output less than 300ps. It offers a low-voltage differential output for PC Board transmission and also features an adjustable DC-coupled differential output.

The MC100LVEP14DTR2 is compatible with current outputs from differential clock sources and can be used in multiple reference clock applications. Its high-impedance inputs, coupled with supply voltage and output drive configuration, allow for minimal power consumption and provide a wide variety of input/output combinations.

Working Principle

The circuit of MC100LVEP14DTR2 consists of six stages. An adaptive control stage is used to maintain output frequencies and match output rise/fall times. This stage is composed of three differential amplifier cells. The output of the adaptive stage is fed to the primary output driver stage. This stage amplifies the signals and drives the external load.

The primary output is connected to the input of the secondary output driver stage. The output of this stage is the active output that is used to drive the external load. The secondary output is connected to the third stage, a low pass filter. The filter attenuates any high frequency components and noise from the input signal.

The fourth stage is a level shift stage. This stage boosts the input signals levels to match the output of the low pass filter. The fifth stage is the output buffer stage. This stage is used to buffer the output of the level shift stage. The buffer stage provides the isolation needed for the output signals.

The sixth and final stage of the circuit is a guard band stage. The guard band stage increases the separation between the positive and negative output signals and prevents any crosstalk between them. In addition, the guard band also provides increased noise immunity and reduces the effects of switching transients.

The MC100LVEP14DTR2 is an ideal choice for high-frequency transmission links, as it can provide a differential frequency of up to 1.5GHz and matched outputs less than 20ps. The wide variety of configurations provide the necessary inputs and outputs needed for various applications. The device also has the ability to minimize power consumption by its low-voltage differential output, high-impedance inputs, and adjustable drive configuration.
