CDCV304PWRG4 is a Clock Buffer IC module which is widely described by its manufacturers Texas Instruments as “an integrated buffer module for a wide variety of clock and data applications”. This application specifically describes how it works and what its primary application field is.

CDCV304PWRG4 is the industry-standard entry-level clock modulator which consists of four wide-band outputs distributed in four banks, making it suitable for multi-channel waveforms such as 2.5V LVDS, LVCMOS, and LVPECL waveforms. Further, its output rate is over 7.50GHz and its output impedance is as low as 50Ω. Moreover, it provides low-skew operation within the 1.00-3.00V logic level ranges and, therefore, is capable of providing better linearity and power savings when compared to LVDS solutions. Its application-level advantages include time-controlled sub-millisecond delay and asymmetrical or simultaneous control of clock and data channels with fixed delays between the two.

When it comes to its working principle, CDCV304PWRG4 utilizes a single-clock modulator that allows synchronization of clock and data signals. It is equipped with a modulator circuit which can take in an input clock signal and generate an output clock signal that is synchronized with the rising edge of the data signal. Furthermore, by using the delay line logic to create a differential pair, the clock and data signals are combined with the output of this modulator circuit split into a two clock-and-data signals. Lastly, the clock output is buffered and the clock and data outputs are externally connected through the differential pair.

Among the applications, CDCV304PWRG4 Clock Buffer IC is mainly used in high-speed clocks, memory systems, and data systems, including networking and communication systems. For example, it can be used in high-bandwidth memory the interface which is constantly demanding high performance clock and data synchronization, or include reduced skew, low jitter and power efficiency. In other words, there are many applications that CDCV304PWRG4 Clock Buffer IC is most suitable for, such as PCIe, DDR3/4, SATA, QPI, and HDMI applications.

To sum up, CDCV304PWRG4 is a Clock/Timing – Clock Buffers, Drivers, which is suitable for reducing skew, low jitter, and power efficiency especially in applications such as PCIe, DDR3/4, SATA, QPI, and HDMI. It is a single clock modulator and consists of four wide band outputs which are distributed in four banks. The input clock rate is over 7.50GHz with an output impedance of 50Ω and it operates within 1.00-3.00V logic level ranges. It is capable of time-controlled sub-millisecond delay and asymmetrical or simultaneous control of clock and data channels with fixed delays between the two.
