The CDCM1804RGET is a low jitter/skew, PCIe-6−compliant clock buffer, driver and generator. It has a wide range of applications in the server, switch, storage, bridge, and USB markets, where a PCIe-6 clock is needed. The CDCM1804RGET offers features such as low jitter (450ps maximum), high frequency-range (−4.4GHz to −6GHz), wide operating temperature range (−40°C to +85°C), low power consumption, and a small footprint with an integrated TSSOP16 package.

The CDCM1804RGET is designed to reduce the number of clock components in a design and to reduce cost, power, and board space. It uses a very advanced clock buffer, driver, and generator architecture which makes it a very attractive solution for demanding applications. It is highly configurable and provides up to 16 independent clock outputs.

One of the main applications of the CDCM1804RGET is its ability to drive PCIe-6 clocks in server and storage environments. The clock can be used to generate the REFCLK signal, which is the main input clock used by PCIe to function properly. The additional features include:

• Designed for low power consumption
• Clock generator supports multiple frequencies
• Up to 16 independent clock outputs
• Low jitter/skew
• Wide operating range
• High frequency range of -4.4GHz to -6GHz

The CDCM1804RGET has a wide range of working principles. The clock generator supplies the REFCLK input which is then buffered and driven out through the Fan-Out buffer stages to the outputs. All of the outputs can be operated independently and have adjustable slew rates as well as other configurable options.

The low jitter/skew makes the device well suited for demanding applications. The CDCM1804RGET supports up to three spread spectrum outputs and up to four programmable skew profiles which can be used to minimize system wide skews between clock pairs or multiple devices. The device also includes a watchdog timer to detect errors in the REFCLK source.

The CDCM1804RGET can also be used for clock swapping, where the device can be configured to output different frequencies than the input frequency. This can be done by reprogramming the device, as well as adjusting the power management profile. The device also supports power down and power up sequencing. These features make the CDCM1804RGET a very attractive solution for designer to optimize design performance.

The CDCM1804RGET offers these features in a very small package, with a 16-pin TSSOP16 footprint. It is designed to reduce board space and cost and to optimize performance. The device is also highly configurable and can be used in multiple applications ranging from server, storage, bridge, and USB markets.

Overall, the CDCM1804RGET is a very attractive solution for demanding applications, where a PCIe-6 clock is needed. It offers many features such as low jitter/skew, high frequency range, wide operating temperature range, low power consumption, and a small footprint. It is highly configurable and can be used in multiple markets such as server, storage, bridge, and USB. It is an ideal solution for clock driving applications as it reduces the number of clock components, cost, power, and board space.
