Programmable Oscillators are used to provide a very wide range of capabilities from frequency generation to spread spectrum clocking. SG-9101CE-D30PHAAB is one such type of programmable oscillator from IDT. The device is a low jitter programmable clock synthesizer integrated chip with a large spread spectrum range of up to ±1.0% for stress-free EMI/ EMC compliance.

The main application field for SG-9101CE-D30PHAAB is in communications, medical, industrial and consumer markets where the requirements for products such as SoC clocking, data acquisition, and networking can be addressed. It has a fully integrated single crystal oscillator with improved power consumption and lower jitter performance than other types of oscillator designs.

Its working principle involves a clock source input in the form of a crystal oscillator, an I2C interface, a frequency selection register, an on-chip non-volatile memory, and a power control logic. The crystal oscillator is used to generate a stable frequency clock signal. The I2C interface allows for high speed communication between the device and the host application. The frequency selection register is used to set the frequency of the output clock signal. The on-chip non-volatile memory is used to store the frequency settings. The power control logic is used to manage the power consumption of the device.

The SG-9101CE-D30PHAAB is capable of operating in a wide range of frequencies from 40 KHz to 819.2 KHz. It offers excellent phase noise performance with very low jitter over the entire range of frequencies. In addition, it is capable of providing the standard LVDS outputs and spread spectrum output options. The power supply voltage range is 2.5V to 3.3V, and the operating current is typically 30 mA. It also features on-chip power-down protection and has internal clock feedback protection.

The device includes a Digital Frequency Synthesis (DFS) technology to improve stability, reduce noise, and improve jitter performance. It is also adaptive to different system frequencies, temperature, and supply voltage which allows it to dynamically adjust the output. The SG-9101CE-D30PHAAB programmable oscillator from IDT offers outstanding accuracy, along with low power consumption, low jitter, frequency flexibility, and spread spectrum capability across a wide range of frequencies. The device is suitable for a variety of communications, medical, industrial, and consumer applications.
