High-Speed PAM Signal Generation and BER Measurement
High-Speed PAM Signal Generation and BER Measurement

... In addition, as described in (b), obtaining a high-quality PAM signal requires that the PPG itself generates high-quality waveforms. If the PPG Jitter is large, the PAM signal Jitter will also be large, and if the waveform distortion is large, the SNR is degraded by the large signal baseline. Any de ...

Discrete Power Supply Solution for Atmel
Discrete Power Supply Solution for Atmel

... Atmel eMPUs have separate power supply inputs for their oscillators and PLL circuits. These analog circuits can be decoupled from the digital (core and I/Os) activity of the device and thus generate less jittered clocks. Atmel highly recommends feeding these power supply inputs with low-noise source ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
