• 9FGV0841AKLF Application Field

The 9FGV0841AKLF is a clock/timing application specific integrated circuit (ASIC) that enables designers to meet the strict power, size, and cost requirements for a wide range of sophisticated communication and display applications. This device integrates several high-performance analog and digital clock/timing functions onto a single chip. These functions include the clock synthesizer (CS), the Flex Clock Interface (FCI), the frequency divider, the voltage controlled oscillator (VCO), the direct memory access (DMA), the programmable logic array (PLA), the phase-locked loop (PLL), the delay-locked loop (DLL), the external clock detection, and the operational delay line (ODL).

• 9FGV0841AKLF Working Principle

The 9FGV0841AKLF clock/timing ASIC is designed to work with very low voltage and require very little power consumptions. The device uses a combination of the clock synthesizer (CS) and the clock interface (FCI) to generate multiple clocks with selectable input and output frequencies. The CS block provides the main clock for the system, while the FCI is used to generate and maintain additional clocks corresponding to different frequencies. The combination of the CS block and the FCI module enables the device to support multiple input/output clock configurations.

The flexible and programmable frequency divider allows the device to support very low-power use cases and a wide range of operating speeds. The VCO pin allows the user to tune in the target frequency, while the DL/PLL combination ensures tight time/frequency synchronization and phase-locks. The DMA controller handles system control, low-speed operation and data transfer protocols, while the programmable logic array (PLA) and operational delay line (ODL) blocks provide tight timing matching and clock multiplexing capabilities.

The external clock detection feature of the 9FGV0841AKLF is used to detect and synchronize to incoming external clock signals. The device is also equipped with an internally generated hardware reset to provide a reliable way to initialize the system after power-up or any power anomaly.

The 9FGV0841AKLF is designed to provide comprehensive clock/timing support for a wide range of applications. The device\'s combination of high-performance analog and digital clock/timing functions ensures the most reliable, accurate and efficient clock/timing design available in the markets today.
