Circuit diagram of a clock generator A desktop PC clock generator, based on the chip ICS 952018AF and 14.3 MHz resonator (on the left) A laptop PC clock generator, based on the Silego chip. A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The output clock signal can range ...
A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e., clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal. [1] NCOs are often used in conjunction with a digital-to-analog converter (DAC) at the output to create a direct digital synthesizer (DDS). [3]
The Yamaha YM2149F SSG (Software-controlled Sound Generator) chip has the same pinout as the AY-3-8910, with the minor difference that pin 26 could halve the master clock if pulled low. If left unconnected, as it would be if replacing an AY-3-8910 chip, an internal resistor pulls the pin high, so the master clock is not halved.
SW17 (toggle or momentary) is the switch that enables the internal noise generator clock. If this switch is closed then the noise generator operates on its internal clock. R29 A 47k fixed resistor. This resistor is in series with SW17 and is the current reference for the internal noise generator clock. In the 76477 spec sheet this is called out ...

The Texas Instruments SN76489 is a programmable sound generator chip from the 1980s, used to create music and sound effects on computers and video game systems. Initially developed by Texas Instruments for its TI-99/4A home computer, it was later updated and widely adopted in systems like the BBC Micro , ColecoVision , IBM PCjr , Sega's Master ...
A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio wave signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation. [1]
27 MHz VCXO clock generator IC (TLSI T73227), used in a DVB-T set-top box. A voltage-controlled crystal oscillator (VCXO) is used for fine adjustment of the operating frequency. The frequency of a voltage-controlled crystal oscillator can be varied a few tens of parts per million (ppm) over a control voltage range of typically 0 to 3 volts ...
