The CDCM1802RGTTG4 is a low-power, high-performance clock buffer, driver, and limit chip. It is typically used in high speed electronic applications that require precise timing. This chip is highly reliable and offers an impressive number of features, including the ability to handle up to 1.2 V output, temperature capability from -40 °C to +125 °C, and a low-skew, low-jitter design. In addition, it has two global clock buffers and four independent outputs, allowing for precise control and scalability.

The primary application field of the CDCM1802RGTTG4 is in the design and manufacture of high-speed digital electronics. These devices are often used to supply the precise clock signals needed for high-speed digital logic and memory devices, as well as for controller designs that require low-skew and low-jitter clock signals. The chip is capable of generating both single-ended and differential clock outputs, with clock frequency up to 133 MHz and output frequency up to 166 MHz. It also includes spread spectrum clock modulation to reduce system EMI/RFI problems, making it an ideal solution for EMI-sensitive applications.

The working principle of the CDCM1802RGTTG4 is fairly simple. It takes a single low-skew, low-jitter input clock, and multiplies it by a factor which can be set through an I2C interface. This multiplied clock is then distributed to four individual PLL outputs, each with its own phase and frequency. The clock outputs are phase-locked to the input clock, giving precise control over timing and frequency. Additionally, the chip has two global buffers to reduce the input clock skew. Spread spectrum clock modulation is also available to reduce system EMI/RFI.

The CDCM1802RGTTG4 is a powerful and reliable device that can be used in a wide range of digital applications. It is capable of generating low-skew and low-jitter clock signals with precise timing and frequency control. The device is also designed to be very low-power, making it ideal for battery-powered applications. Furthermore, it has spread spectrum modulation for EMI reduction, making it a great choice for noise-sensitive designs. The chip is highly reliable and offers excellent performance for its price.

In summary, the CDCM1802RGTTG4 clock buffer, driver, and limiter chip is a versatile, low-power device for precise timing and frequency control in high-speed digital electronic applications. It has two global clock buffers and four independent outputs, allowing for precise control and scalability. It also includes spread spectrum clock modulation to reduce system EMI/RFI problems, making it an ideal solution for EMI-sensitive applications.
