SIT1602BCT1-28E

Programmable oscillators provide control of the frequency and timing output signals, which has been a great innovative concept in a broad range of applications.

The SIT1602BCT1-28E, manufactured by Sameer Technologies, Inc., is a fully programmable 32 bit oscillator specifically designed as a clock and frequency synthesizer targeting radio frequency (RF) applications.

The core device of the SIT1602BCT1-28E is a 32 bit OTP (One Time Programmable) memory which is programmed in the factory. The product specifications defines the device operating range, which is from 0.3 v to 3.3v, with a typical frequency of 5.25MHz, 8MHz and 12MHz. The frequency of the outputs are synthesized from the memory which then, drives the PLL with a patented “Adaptive Path” technology.

The PLL is optimized for precise frequency calibration of the output with minimal jitter and phase noise. The minimum tuning resolution is 500kHz and the performance of the PLL is independent of the input duty cycle.

The SIT1602BCT1-28E also includes low jitter outputs that can be used to generate multiple differential clock outputs. The output clock pitch is offered in 48-pins LQFP and BGA packages. The oscillators have an operating temperature range of -25ºC ~+85ºC and output a wide range of selectable frequencies in a wide range of applications.

The device is used in a wide range of applications, such as in high speed data transfer, communications, industrial, consumer and instrumentation systems. It also supports applications requiring precise frequency and timing control such as radio base station transceivers, multimedia/wireless communication systems, aerospace/defence industries, and medical instruments.

The application field and working principle of SIT1602BCT1-28E oscillators can be summarized as the following: the device is a fully programmable 32 bit oscillator that supports applications requiring precise frequency and timing control with an operating range from 0.3v to 3.3v, with a typical frequency of 5.25MHz, 8MHz and 12MHz. The product specifications defines the device, with the frequency of the outputs being synthesized from its memory, then, drives the PLL with a patented “Adaptive Path” technology. The PLL is optimized for precise frequency calibration of the output with minimal jitter and phase noise. The device can be used in a wide range of applications, where precise frequency and timing control required, with an operating temperature range of -25ºC ~+85ºC and output a wide range of selectable frequencies.

In conclusion, the SIT1602BCT1-28E oscillator is a great device for those applications requiring precise frequency and timing control. It offers a wide operating range, a low jitter outputs and an input duty cycle that is independent from the PLL. It is a great addition to the Programmable oscillators family.
