Silicon Oscillators
Analog Devices silicon oscillators are frequency programmable via pin-strapping, or through the resistor connection or serial interface (SPI or I2C). These solid-state clocks are well-suited for general-purpose usage, such as PGAs, ASICS, microprocessors, or UARTS, and they operate from 1 kHz to 170 MHz. Silicon oscillators are also ideal switching regulator clocks as they provide synchronization and EMI reduction (via spread spectrum).

1000W Ferroresonant Power Supply
Series PRR
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.

Oscillators for Radio Amateurs
An oscillator is an electronic circuit designed to produce either audio or radio frequency signals. These will generally have sineusoidal wave form, but other wave shapes such as square and sawtooth are possible. In radio equipment oscillators will always have a low output power, and if a radio frequency is produced, the oscillator is acually a basic radio transmitter.
