PCS2I2309NZG16SR is a clock buffer/driver IC that is compatible with various 3.3V and 5V CMOS and LVPECL applications. It provides programmable output frequency and delay between outputs, which makes the IC suitable for many applications where mininizing delay between clock outputs and differentiating discrete frequencies is required. The paper will discuss PCS2I2309NZG16SR application fields and working principles in detail.

Application Fields of PCS2I2309NZG16SR

PCS2I2309NZG16SR is a dual-input, multiple output (DMO) clock buffer, which can provide up to 8 low-skew, high-jitter output clocks. It provides high-performance, consistent and reliable clock distribution through multiple outputs. PCS2I2309NZG16SR can be used in various computer networking applications, where multi-phase frequency generation and distribution is a requirement.

It can also be used in high-speed digital signal processors and controllers where accuracy, timing and jitter requirements are stringent. It can be used in data communication systems for driving long lines, and in memory buffering systems.

Working Principle of PCS2I2309NZG16SR

PCS2I2309NZG16SR is essentially a dual-input multiple output (DMO) clock buffer with programmable output signal frequency and delay between outputs. It is powered by an internally regulated 3.3V power supply, and can accept a wide range of input voltage levels, such as 3.3V (CMOS), 5V (CMOS), LVPECL, and 3.3V/5V (LSTTL).

The chip has a dual-input circuit that can select either of the two input clocks and route them to the output pins. The input selection circuit is controlled by an internal programmable control logic, which routes the selected input clock to the outputs. The chip also has a low-noise, monolithic PLL circuitry that can provide precise frequency and precise timing for the output clocks.

The chip has an adjustable slew rate up to 100ps. It also has a built-in power-derating circuitry to prevent possible IC overheating due to the high output frequencies. It has precise output skew, low jitter and wide range of output frequency from 20MHz to 400MHz.

The output pins are divided into two groups, the fast outputs and the slow outputs, each group having its own internal selectable delay for precise frequency and timing control. The outputs can be separated into nine distinct delays for different clock frequencies, providing consistent and reliable clock distribution.

Conclusion

PCS2I2309NZG16SR is an ideal clock buffer/driver IC for various 3.3V and 5V CMOS and LVPECL applications, such as those found in computer networking applications, high-speed digital signal processors and controllers, data communication systems, and memory buffering systems. It features dual-input circuit, low-noise monolithic PLL, adjustable slew rate up to 100ps, power-derating circuitry, precise output skew, low jitter and wide range of output frequency from 20MHz to 400MHz, and programmable output frequency and delay between outputs. In summary, PCS2I2309NZG16SR is a great choice for applications requiring precise frequency and timing accuracy.
