Programmable Oscillators

The SG-9101CG-D40PGBAC is a type of programmable oscillator used to generate frequencies within the range of 10 to 250 MHZ. It is designed to deliver reliable frequency performance at various temperatures and crystal oscillators, that have both low power consumption and ultra-low jitter.

Application Field

The SG-9101CG-D40PGBAC has wide ranging applications, as it can be used in any device which requires precision timing. Particularly, it is commonly used as a reference clock for FPGA and DSP based designs, and embedded applications.

The SG-9101CG-D40PGBAC is also widely used in industrial products, such as frequency synthesizers, cellular baseband, fixed wireless baseband and server products. Besides, the programmable oscillator can be applied to communication system, digital television systems, consumer electronics, medical instruments, computer and test equipment.

Working Principle

In order to generate precise frequency, SG-9101CG-D40PGBAC programmable oscillator integrates a low jitter fixed frequency silicon oscillator and an additional 1-kHz to 500EMHZ frequency synthesizer pass to generate frequency output. The output frequency is made up of the sum of both frequencies with a resolution of 1kHz.

In frequency tuning, SG-9101CG-D40PGBAC utilizes programmable divider registers which offers customers options for different output frequency, for example, a 5.0MHz clock can be produced from a 250MHz input frequency by setting the divider registers to 50.

As for controlling and monitoring, the chip has numerous configurations that provide the user the freedom to select different output frequencies, frequencies of synthesizers and power up modes.

On the other hand, the SG-9101CG-D40PGBAC has options for several power up modes for different power consumption and stability. For example, a fast start- up mode consumes more power but provides stability faster than a slow start-up mode. The user can select the optimal power up mode depending on the application requirement.

In terms of power consumption, the programmable oscillator consumes very low power, providing an improved solution for customers. It delivers a maximum of 35mA and a typical of 20mA at 25M HZ.

Moreover, SG-9101CG-D40PGBAC integrates TTL, CMOS and LVDS outputs, providing options for different industry standards.

Overall, the SG-9101CG-D40PGBAC programmable oscillator is a highly programmable and power saving solution, which is why it is widely used in various industrial applications.
