843252AG-45LF

The 843252AG-45LF is a versatile clock generator, phase locked loop (PLL) and frequency synthesizer. It combines a clock generator, voltage-controlled oscillator (VCO) and a dual modulus divider/prescaler all in one integrated circuit (IC). The device is targeted to applications requiring a low-power generator with high performance and low jitter.

The principal application for the 843252AG-45LF is in clocking and timing systems. These systems typically require a low-jitter and high-frequency clock source for operations requiring precise synchronisation and accurate timing. The 843252AG-45LF is capable of producing a clock output of up to 125 MHz, and a frequency synthesis output of up to 25 MHz. It also produces a low-jitter clock to accurately synchronise data transfers, control other system blocks and control peripheral logic.

The 843252AG-45LF is capable of operating in several different modes. In the frequency synthesis mode, it can produce a single frequency output. In the frequency division mode, it can divide a high frequency clock output by an integer factor with low jitter and high accuracy. In the clock synchronisation mode, it can divide the frequency of a reference clock by an integer factor, providing accurate phase locking and low jitter to the output frequency.

The 843252AG-45LF also features several different functions to control and adjust its output frequency. An internal voltage-controlled oscillator (VCO) allows the output frequency to be adjusted depending on the voltage applied to it. This is particularly useful for applications where the frequency needs to be adjusted dynamically. The device also features an on-chip automatic gain control (AGC) to regulate the VCO frequency for optimal performance. The 843252AG-45LF has programmable loop bandwidth and a fully integrated phase/frequency detector to ensure precise lock of the output frequency.

The 843252AG-45LF also includes a number of additional features, such as an integrated crystal oscillator, reference clock select and a digital logic input circuit to enable synchronous programming of the loop bandwidth and output frequency. It is also capable of synchronising to an external clock, allowing the output frequency to be synchronised to an optical, radio frequency or other reference clock source. The device has extremely low power consumption, making it ideal for applications where power consumption is a critical factor.

In conclusion, the 843252AG-45LF is an ideal device for applications requiring a compact and low-power clock generator, PLL and frequency synthesizer. It combines a versatile feature set with outstanding performance and low power consumption, making it ideal for applications such as clocking, timing and frequency synthesis. The 843252AG-45LF is an excellent choice for a wide range of embedded systems requiring high-accuracy, low-power operation.
