Application Field

ASM3I2779AF-06OR is a versatile solution for a variety of applications including telecom networks, HDTV, enterprise wired networks, broadcast TV, consumer electronics, and wireless networks. It is capable of providing up to 250MHz output frequencies and can be easily programmed to provide multiple clock outputs. The device is specifically designed for applications that require reliable and accurate timing/synchronization of electrical signals. It can also be used in applications that require a wide range of frequency support, including digital video and audio.

Working Principle

The ASM3I2779AF-06OR device consists of an on-chip differential clock generator, phase locked loop (PLL), and frequency synthesizer. The differential output clock generator uses Multi-Output Frequency-Locked Loop (MOFLL) technology to generate a low-sensitivity, low-jitter, low-noise clock signal. The generated clock signal is then outputted as either a single-ended or differential clock signal. The on-chip PLL enables the device to provide frequency synthesizer capabilities by locking the output clock frequency to an external reference clock signal. The device can also be programmed to provide up to two clock output frequencies.The output clock frequencies of ASM3I2779AF-06OR are programmed by a serial control port. This serial port can be connected to a microprocessor or other host system to provide greater flexibility in the configuration, programming, and operation of the device. The device can also be programmed to provide various output clock frequency ranges and divide ratios, allowing it to generate a wide range of wideband output clocks. The device’s internal PLL enables it to lock the output clock frequency to an external reference clock signal, while the ability to program the device to provide different output clock frequencies, enables it to be used in applications that require a wide range of frequency support. In addition,the on-chip differential output clock generator also supports the generation of sine and pulsed waveforms for timing applications. This allows the device to be used in applications that require clock signals with specific waveforms and shapes.

Conclusion

ASM3I2779AF-06OR is an ideal solution for a variety of timing/synchronization applications, including telecom networks, HDTV, enterprise wired networks, broadcast TV, consumer electronics, and wireless networks. It provides up to 250MHz output frequencies and can be easily programmed to provide multiple clock outputs. Its on-chip PLL and frequency synthesizer enable the device to generate a variety of frequencies, while its on-chip clock generator offers low-jitter, low-noise, low-sensitivity generation of both single-ended and differential clock signals. The device’s programming flexibility also makes it ideal for applications that require a wide range of output clock frequencies.
