Generating PAM4 Signaling For Receiver Compliance Testing

Generating PAM4 Signaling For Receiver Compliance Testing PAM4 Signaling Overview PAM4 signaling has gained popularity over the past few years with serial data rates approaching 56Gb/s per channel. This more bandwidth efficient 4-level signal modulation technique (compared to the simpler 2-level signal modulation technique (PAM2) that is most commonly referred to as NRZ) avoids the […]

PRBS Generators

The ADSANTEC family of PRBS generators provides the generation of high fidelity pseudo-random binary sequence (2n-1 format) data signals for testing high speed components. These low cost, compact generators cover a frequency range from 10 kb/s to 64 Gb/s, with amplitudes up to 1.6 V pp differential and low jitter, fast rise/fall times. The PRBS […]

Is A Coupler The Same As A Power Divider?

Couplers and power dividers are two of the most fundamental components of electronic devices used for the transmission and reception of radio waves. They both are classified as passive Radio Frequency (RF) components and can be found in almost every electronic device that is used for telecommunication purposes. Many people think that couplers and power […]

Why We Need Logic Level Converters

There are instances when a system designer is utilizing numerous components whose power supply levels don’t match. In most cases, AC coupling of the parts together while incorporating resistive networks to set proper voltage bias points if needed is utilized. This kind of strategy doesn’t work though when the signaling in between the two parts […]

Why Do We Need Analog To Digital Converters?

Any physical signal, such as a sound, or a light, or a voltage, is considered an analog signal. The thing about analog signals is that they are infinite in nature. There are infinite numbers of sounds we can hear, there are infinite colors to perceive, and there are infinite numbers between the 1 and 2. […]

All About Application-Specific Integrated Circuits (ASIC)

An application-specific integrated circuit (ASIC) is a custom-made integrated circuit designed only for a specific use, and not intended for general purpose. They are used in a number of fields such as automotive, medical, telecommunication and industrial sector. An ASIC chip is used in modems, satellites, Bitcoin miners, voice recorder equipment, etc. ASIC has changed […]

Digital Pre-emphasis

Digital Pre-emphasis: Overcome Transmission Channel Nonlinearities with a Digital Pre-emphasis Amplifier A data signal with the appropriate amount of applied digital pre-emphasis (or de-emphasis) is able to counteract the nonlinear gain effects of the transmission medium in is traveling in. There gain nonlinearities lead to the various frequency components of the data signal experiencing non-equal […]

Delay Line

Delay Line: Ensure Critical System Timing Points are met using a Signal Delay Line A signal delay line is a product that takes an input signal (in this case a clock or data signal using high speed CML) and outputs it at a fixed delay that is slightly adjustable. Adjustment can be either through digital […]

Active Analog Splitter

Active Analog Splitter: Leveraging an Active Analog Splitter to Increase an ADC System’s Sampling Rate A common know method to increase the sampling rate of an ADC is to position two or more of them in parallel and sample their inputs at different phases of the system’s sampling signal (usually a standard clock signal). For […]
