CDCV304TPWREP is a type of high frequency clock buffer/driver, which is designed with 4 output channels. It is a low power, low skew, low jitter device that works at high frequencies up to 999MHz, thus is an ideal choice for high speed clock tree applications. Due to its feature of low power consumption, CDCV304TPWREP is also applicable for situations where power is limited.

Application Field

CDCV304TPWREP is mainly applied for clock signal conditionings, such as fan-out, broadcasting, buffering, signal integrity improvement, and signal isolation etc. It is mostly used in servers, desktop PCs, networks, and communications etc. where high speed, low jitter, and low skew are mandatory. Other application fields include enterprise systems, graphics cards, motherboards, and storage systems.

Working Principle

CDCV304TPWREP is based on a voltage oscillator and differential amplifier architecture to achieve high levels of performance. A differential amplifier is used to increase the input clock differential signal magnitude and to reject any disturbances that may come from external grounds or devices. The Voltage Controlled Oscillator (VCO) is configured to detect the clock signals and to generate the corresponding output response according to a predetermined frequency. A terminator, typically a 50 ohm resistor, is put at the output of the differential amplifier to avoid any reflections and transmission errors so the output is stable and reliable.

The output of the differential amplifier is then amplified and buffered to the final output. The buffering part is actually achieved by driving individual transistors with the output of the differential amplifier, providing clean and isolated outputs. Therefore, CDCV304TPWREP also offers a wide range of output levels between 1.3 and 3.3V, allowing it to be compatible with different kinds of logic families, such as LVCMOS, LVCMOS25, LVCMOS33, and HSTL etc.

Finally, one of the most defining features of this particular clock buffer/driver is its frequency operation range, which is up to 999MHz, allowing it to meet the clock requirements of today’s most demanding applications. The device can be operated both in single-ended and differential mode by configuring the clock input correctly. It also has an internal monitoring mode, which is used to ensure reliable operation even in extreme or noisy conditions.

In summary, CDCV304TPWREP is an ideal clock buffer/driver for high performance application fields, such as Ethernet, data transfer, and storage systems, due to its features of low power consumption, low jitter, low skew and high frequency operation. The device can be configured to accommodate different logic families, making it both flexible and reliable.
