The 8440258CK-46LF is a Clock/Timing generator, PLL (Phase Lock Loop) frequency synthesizer, and high performance clock generator for note and laptop PCs, POS terminals, and industrial applications. This chip is designed to provide high-definition digital audio/video signals, and can be used in many timing and rate conversion applications. This chip is configured as a 12-bit, single-reference, DC-coupled PLL with a wide input frequency range (200 kHz to 900 MHz). The 8440258CK-46LF has five main functions: frequency synthesis, frequency conversion, frequency and rate control, rate matching, and clock conditioning.

The most important feature of the 8440258CK-46LF is the DC-coupled architecture. This allows for a much larger input range and faster lock times than traditional, AC-coupled PLLs. The device offers three different reference clock inputs: an analog reference, a digital reference, and a fault clock (FC). All three inputs can be used to provide a reference frequency of up to 100 MHz. The programmable divider within the chip allows for great flexibility in the timing and rate conversion of the design. The full-function clock generator offers both internal and external divide-by-2 stages, an overflow detection circuit, and a programmable pre-scaler.

The 8440258CK-46LF provides the user with precise frequency synthesis capabilities. This is possible thanks to the design features of the chip, including a VCO (Voltage Controlled Oscillator), phase detector, and charge pump combination. The frequency synthesizer incorporates an advanced phase-detect algorithm and a programmable phase detector range, allowing for extremely precise frequency synthesis. The charge pump can be programmed for a variety of power supply ranges, and can be used to supply the VCO with precise tuning voltages. It also provides a very efficient noise reduction scheme.

The 8440258CK-46LF is an ideal choice for timing applications. The ultra-low jitter, low-power capability, and wide range of programmable parameters makes this chip ideal for use in a wide range of applications. Its wide input range, low power consumption, and high accuracy are also excellent for use in notebook, POS, and industrial applications. This chip is an excellent choice for high-frequency applications requiring precise control over frequency, phase, and timing. It is designed to offer maximum flexibility and high performance in a wide variety of applications.
