PCK2111BD is a high performance, high frequency clock buffer used for a variety of applications. It is designed to support a wide range of clock signals up to 375MHz. PCK2111BD is a well-suited choice for applications requiring low jitter and low power consumption. The clock buffer is also qualified to deliver better performance than competing solutions in terms of jitter and power consumption.

Application Field : PCK2111BD is used in a variety of applications including clocking, timing, synchronization and signal management. It is suitable for a wide range of high-speed serial link applications, such as Gigabit Ethernet, fibre channel and Serial ATA. It is also designed for use in frequency synthesizers, Global Navigation Satellite Systems, personal computers and microprocessor-based systems.

Working Principle : PCK2111BD is an 8-output clock buffer which accepts a wide range of frequency inputs. It uses a high-performance, low-power design making it suitable for applications where power consumption is critical. The clock buffer uses a supplied source to clock all outputs with a 3-state enable input to disable any of the outputs. PCK2111BD supports a wide range of input frequencies up to 375MHz and provides very low jitter performance.

The clock buffer uses a PLL (phase-locked loop) to generate the clock output signals. The PLL is designed to track a wide range of input frequencies and adapts its parameters to the given input signal. This allows the clock buffer to generate very low jitter clocks with no additional calibration steps.

The clock buffer also features on-chip spread spectrum clocking which is designed to reduce EMI emissions from the device. This feature can be disabled if required. PCK2111BD also features a power down mode, allowing the device to be turned off when not in use. This can dramatically reduce power consumption in applications where the buffers are not constantly enabled.

PCK2111BD is a low-power, low-jitter clock buffer, ideally suited to high-speed serial link applications. Its wide range of input frequencies and low jitter performance make it a great choice for applications requiring reliable and accurate timing.
