It incorporates an NTSC/PAL video input port, integrated Analog-to-Digital Converter (ADC) with Phase Lock Loop (PLL) and LVDS transmitters.
Products include amplifiers, attenuators, data converters, frequency dividers and detectors, frequency multipliers, high speed digital logic, interface, limiting amplifiers, mixers and converters, modulators and demodulators, oscillators, passives, phase lock loop (PLL), phase shifters, power detectors, sensors, switches, synthesizers, transimpedance amplifiers and variable gain amplifiers.
He then covers phase lock in noise including modulation by noise, response to phase noise, representations of additive noise, loop response to additive noise, phase-locked loop as a demodulator, parameter variation due to noise, cycle skipping due to noise, nonlinear operators in a locked loop, acquisition aids in the presence of noise, and bandlimited noise.
