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 […]
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 […]
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 […]
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 […]
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. […]
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: 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 […]
High speed analog to digital converter: A Low Latency 4-bit High Speed Analog to Digital Converter Conversion of analog signals into its digital representation is needed everywhere in the electronics world. The analog signals can be created in many different ways, for example, produced by sound into a microphone or light entering a camera etc. […]
Four channel PRBS generator: A Flexible User Friendly Four Channel PRBS Generator A new product release by ADSASNTEC Inc. is a 0.1-40Gb/s four channel pseudorandom binary sequence (PRBS) generator featuring custom word functionality. The two choices for PRBS pattern lengths at the output are PRBS 27-1 (PRBS7) and PRBS 211-1. Up to 1.0Mbit customized data words […]
Clock Splitter: An Active High Frequency Clock Splitter An effective method to disburse a needed synchronizing clock signal throughout a system is by employing an active clock splitter. Compared to a passive solution, an active device delivers gain amplification, which is useful when signal restoration is required. As opposed to larger mechanical designs, active solutions […]
Clock Distributor: Effectively Synchronize Your System with a Clock Distributor To ensure the different electronic sections of one’s system are synchronized correctly one must employ an effective clocking strategy. This is especially true when building test and measurement equipment like a multichannel high data rate PRBS / pattern generator. Not only do parts in series […]
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: 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 […]
Contrary to popular belief, power splitters and power dividers are NOT the same thing! The fact that both of them are passive radio frequency elements, and have similar names has caused a bit of confusion in most circles. To put an end to this, we’ve written a short piece analyzing the difference between the two.
In the world of digital signal processing, the importance of analog to digital conversion can never be understated. These devices play an important role in simplifying signal processing by making things easier for engineers and analysts.
