The CY29948AC is a clock and data buffer for differential output applications and is designed for 3.3-V applications. It is available in a 16-pin DIP package.

The CY29948AC features up to 4 GHz performance. It is designed with two independent differential outputs and can fully buffer up to two data signals. The CY29948AC uses the same high speed performance and low power consumption as other Cypress clock and data buffers.

The CY29948AC is suitable for QDR (Quad Data Rate) SDRAM, RDRAM, and graphics applications. It can also be used in networking, storage, storage/signal interface, and communications applications. It features an Ultra-low jitter mode, offering improved jitter performance over standard buffers.

The CY29948AC offers different operating modes for different needs. For example, Continuous Clock Mode (CCM), Triple Speed Clock Mode (TSCM), and Alternate Clock Mode (ACM). In CCM, the input clock is passed directly to the output. In TSCM, two additional clocks are generated and passed to two additional outputs. In ACM, the module can be used to generate an output clock from two input clocks.

The CY29948AC also reduces EMI noise by providing very low power dissipation, reducing output skew and jitter, and providing significantly less power supply noise. It offers very high ESD protection (up to 16 kV) and low power dissipation of only 25 mW at 4.5 V.

The CY29948AC supports a wide range of frequencies and is designed for a range of 3.2 to 3.5 GHz. It has a logic delay of 1.0 ns and an open circuit output of 2.0 ns. The CY29948AC is capable of operating on a single 3.3-V supply voltage.

The CY29948AC can be used in applications such as storage systems, signal processing, portable LCDs, and more. It is designed for high performance and reliability, and is ideal for use in low-power and high-speed applications such as PCIe, GDDR, and various imaging applications.

The working principle of the CY29948AC is quite simple. When an incoming clock signal is received, the module takes the signal and divides it into two output signals of complementary polarities. The complementary output signals are then amplified and sent to the outputs. The CY29948AC is then ready to receive the next input signal and repeat the cycle.

The CY29948AC offers an efficient clock and data buffering solution for 3.3-V applications. Its high speed performance, good power consumption, and support for multiple operating modes make it ideal for a wide range of applications. With its low jitter and output skew, the CY29948AC offers a reliable and cost-effective clock and data buffering solution.
