SG-9101CG-D40PGCCA

Programmable Oscillators

Programmable oscillators are electronic components that generate a steady, repetitive electronic or acoustic signal, or both. The most common type of programmable oscillator is a voltage-controlled oscillator (VCO). VCOs are used in many applications, including music synthesizers, digital clocks, cell phones, and computer peripherals. The SG-9101CG-D40PGCCA is an example of a VCO manufactured by SGS-Thomson Microelectronics.

SG-9101CG-D40PGCCA Application Fields and Working Principle

The SG-9101CG-D40PGCCA is a low-power programmable oscillator designed for use in cellular phone and GSM communication devices. This VCO is designed for operation with a wide range of supply voltages and has an operating temperature range of -40°C to +85°C. The device is also capable of operating at frequencies of up to 110 MHz.

The SG-9101CG-D40PGCCA utilizes a dual-modulus frequency divider to achieve higher frequency requirements. The device also includes a p-channel transistor, which is used to control the frequency divider. The transistor is driven by a control voltage, which is generated via a voltage reference. This voltage reference is inputted via one of two frequency control pins.

The operation of the SG-9101CG-D40PGCCA can be described as follows. The device receives an input frequency via one of the two frequency control pins. This frequency is then directed to the dual-modulus frequency divider, where it is divided by a predetermined ratio. This ratio is controlled by the voltage reference, which is inputted via the other frequency control pin. The output from the dual-modulus frequency divider is then used to generate the output signal.
