The MAX9485ETP-T is a low-power, highly-integrated, single output clock generator with integrated PLL (Phase Locked Loop) and defines a new level of low-power, lower noise and improved PLL performance. This device is designed for portable, mobile and automotive applications, providing a simple and cost-effective solution for applications that require a high-performance, single output clock generator with integrated PLL.

The MAX9485ETP-T consists of two building blocks, a voltage-controlled oscillator (VCO) and a PLL. The VCO consists of a high-performance p-type polysilicon self-biased resistor and an oscillator circuit, which is automatically tuned to the desired frequency. The PLL includes a simple analog linear-feedback loop control, which produces a stable and accurate clock signal with minimal jitter.

The MAX9485ETP-T is ideal for applications such as microprocessors, peripheral components, communication interface circuits and converters. It enables the delivery of high-performance, low-noise clock signals and provides a low-cost solution for frequency generation requirements.

The main features of MAX9485ETP-T include:

• Highly integrated—no external components required
• Integrated PLL
• Low-power consumption with full-integrated PMOS switch
• Low phase noise and jitter performance
• Wide range input frequency—from 0.1 to 1 MHz
• High-accuracy PLLs for low noise and jitter
• Integrated PMOS switch for power saving
• Multi-channel PLL for up to four independent clock signals

The working principle of the MAX9485ETP-T is as follows. The circuit starts with an input clock signal, which is utilized by the PLL to provide a stable and accurate clock signal with minimal jitter. The input signal is converted to a voltage signal, which is then multiplied by the VCO. This signal then goes through the PLL, which filters out the jitter, low pass filters the signal, and produces a low-jitter, stable signal.

The MAX9485ETP-T is designed to provide a low-power, low-jitter, and cost-efficient solution for frequency generated requirement in clock-generator applications. The device employs a highly-integrated platform, which eliminates the need for external components, resulting in a low-cost and efficient solution for frequency generation needs. The device is ideal for applications such as microprocessors, communication interface circuits and converters.
