9DMU0141AKILF

The 9DMU0141AKILF is a frequency synthesizer that operates in the 1.25 GHz to 1.75 GHz range. The device is designed to provide high accuracy, repeatability and reliability to telecommunications and other communications systems. It is a clock/timing-application specific solution, with features and functionality designed specifically to meet the rigorous requirements of telecommunications systems.

The 9DMU0141AKILF consists of a base oscillator, a frequency synthesizer, a divider, a multiplexer and an output amplifier. The base oscillator is used to generate a fundamental frequency that is modulated by the synthesizer for a stable, high-accuracy output. The synthesizer consists of a digital phase-locked loop (PLL) to provide a wide range of output frequencies with low phase noise and jitter. The divider is used to divide the synthesizer output for generating frequencies that are integer multiples of the fundamental frequency. The multiplexer is used to select a specific output frequency from among the multiple possible outputs generated by the synthesizer. The output amplifier then amplifies the selected output frequency.

The 9DMU0141AKILF features several types of clock input signals: LVCMOS, SCK, LVCMOSD2 and XTAL. These inputs provide several features to make the device more suitable for a variety of applications. The LVCMOS input allows the use of external PLLs or other clock sources. The SCK input allows synchronization of the frequency synthesizer with external signals, and the LVCMOSD2 input provides an alternative clock input option. The XTAL input provides a more accurate clock signal for use in high-accuracy, low-jitter systems. Additionally, the device supports operation from 1.25 to 1.75 GHz with input voltages from 0.8 V to 2.5 V.

The 9DMU0141AKILF also has several features necessary for emergency operations in which low power and high reliability are required. These include an integrated power-on reset circuit for reliable system operation, a programmable watchdog timer for resetting and cycling the system in the event of a fault, an emergency override function for returning the system to its default state in the event of a fault, and an emergency power-down mode for reducing the power consumption of the system during emergency operations.

In addition to its features and functionality, the 9DMU0141AKILF provides high accuracy, repeatability, and reliability. The device is designed to meet severe required specifications in areas such as reference jitter, phase-noise, and spurious spectra, while maintaining low power consumption. Its extremely low reference jitter of 0.3 ps rms makes it ideal for critical clock/timing applications.

The 9DMU0141AKILF is an ideal clock/timing-application specific solution for telecommunications systems. Its wide range of inputs, low power requirements, high accuracy, and reliable operation make it suitable for a variety of system requirements. Its advanced features, including emergency override and power-down modes, guarantee reliable system operation in any circumstance. With its low reference jitter, the device can meet the demands of any demanding communications system.
