Introduction:The 8T49N524-007NLGI8 is a member of the 8T49N5xx family of CMOS clock generators and synthesizers that offers fast switching in PLL frequency and wide operating range. This versatile device is designed to meet low-noise, low jitter and low power requirements while improving system performance. The 8T49N51x family produces output frequencies up to 8Ghz and supports multiple output formats, such as LVDS, LVPECL, CML, and heavy-load terminated or un-terminated outputs. Application fields and working principle:The 8T49N524-007NLGI8 is a versatile clock generator used in various applications like networking, high data rate communication and military systems. It enables synchronization of clocks between different nodes in a network, at very high data rate. The 8T49N524-007NLGI8 clock generator divides the input clock signal from a high-performance crystal oscillator, then uses the feedback signal from the outputs to create a precise frequency in the ambient Reference Frequency Multiplier. The Compare Frequency register and the Phase Comparator then adjusts the reference frequency and the current frequency until the incoming PLL signal is reached. The 8T49N524-007NLGI8 includes a digital-to-analog converter (DAC) providing high margin of frequency and compliance.Features:The 8T49N524-007NLGI8 provides very low jitter (pJ) minimizing timing errors and reducing data errors; also, it supports low standby current consumption of 4ma. The device consists of a PLL clock generator and a divide-by-N prescaler with four different outputs. The prescaler offers the option to use external ODEL or IDEL to select the output frequency. Additionally, the 8T49N524-007NLGI8 includes an adjustable divide-by-N control, in which the middle four outputs can be individually adjusted, allowing for a wide operating frequency range. Conclusion:The 8T49N524-007NLGI8 is a versatile clock generator and frequency synthesizer used in various applications for high-performance networks, high data rate communication, and military systems. This clock generator offers low-power, low-noise and low jitter performance and reduces data errors. The flexible design allows for a wide range of operating frequencies and is easy to implement with external ODEL/IDEL. In conclusion, the 8T49N524-007NLGI8 is a great choice for clock generation and frequency synthesis applications.
