601G-21LF

The 601G-21LF is a programmable clock generator (crystal oscillator) manufactured by IDT. It is a clock generator that has a digital output at one end and an oscillator clock input at the other. The 601G-21LF has two main application fields. One field is the frequency synthesis where it is used to generate a precise and clean clock frequency. The other field is clock synchronization, where it is used to synchronize the operation of two clock oscillators.

What is 601G-21LF?

The 601G-21LF is a low-cost programmable clock generator that can generate or synthesize clock frequencies from 10 MHz to 600 MHz. It has a built-in programmable frequency synthesizer that can produce clock frequencies that are accurate and clean. The 601G-21LF can be programmed to generate a low-jitter clock of any frequency, within its range, with a frequency step resolution of 0.001 Hz.

Applications of 601G-21LF

The 601G-21LF can be used to generate or synthesize clock frequencies for various applications, including embedded computing, radio communications, and other digital systems. It can also be used to generate or synchronize the operation of two clock oscillators.

Working Principle of 601G-21LF

The 601G-21LF uses a frequency synthesizer to generate or synthesize the clock frequency. It starts by applying an input clock of either 10 MHz or 16 MHz at the digital input stage. This input clock is then divided down to the programmed output clock frequency. The frequency synthesizer then uses a combination of programmable dividers and registers to adjust the output clock frequency and ensure low jitter.

The 601G-21LF also has an adjustable output drive strength, ranging from 0 to 4V, which can be used to adjust the output current. This allows the user to easily adjust the output current to match the current requirements of the system.

The 601G-21LF also has an integrated temperature-compensated crystal oscillator (TCXO) which helps to reduce jitter and improve the accuracy of the output frequency.

Conclusion

The 601G-21LF is a low-cost programmable clock generator designed for applications that require accurate and clean clock outputs. It can be used to generate or synthesize frequencies from 10 MHz to 600 MHz, and can also be used to synchronize the operation of two clock oscillators. Its built-in frequency synthesizer, adjustable output drive strength, and TCXO make it an ideal solution for a wide range of clocks and timing applications.
