The LMK00308SQE/NOPB is a fanout clock buffer, offering an innovative and efficient way to many clock fanout applications, distributing a single input into multiple outputs. This application field and working principle can be found in many leading edge products that require the combination of low power, low skew, high jitter performance, and fast switching characteristics.

The clock fanout buffer is typically utilized in high-speed systems to reduce board area and maintain timing requirements. This product offers a number of convenient features such as an adjustable input slew rate and adjustable output drive level as well as a wide operating temperature range. It can also easily accommodate a wide range of input frequencies, further enhancing its flexibility.

The LMK00308SQE/NOPB can support fanout of one or two clock signals, up to 16 outputs. The input or outputs can be sourced from TTL, LVCMOS or CML. Its low-voltage and low-power operation make it ideal for saving power and cost in microprocessor, FPGA and communication applications.

The working principle of the LMK00308SQE/NOPB is based on a combination of high-performance clock distribution and buffering. The device utilizes a proprietary bi-directional clock synthesis engine (DPCLK) that is capable of handling wide frequency ranges while delivering an excellent jitter performance. The output of this engine is fed into a circular buffer, which is then multiplexed to the outputs on demand.

The clock buffering and distribution characteristics of the LMK00308SQE/NOPB result in excellent performance in many situations. The low power consumption makes it an ideal solution for always-on applications where power consumption is a major concern. Additionally, the wide frequency range, the low slew-rate, the low jitter, and the fast switching speed make the device highly suitable for processor systems that require a high degree of synchronization and timing accuracy.

The LMK00308SQE/NOPB is available in two packages, SOP8 and QSOP16. The DIP package also supports up to two clock outputs with a frequency up to 132 MHz. The device is backward compatible with other devices in the LMK00308 family and is also compliant to IEC 62103 safety standards.

In conclusion, the LMK00308SQE/NOPB is an advanced clock buffer suitable for a variety of clock fanout applications. The wide frequency range, low power consumption, low jitter performance and fast switching features make the device ideal for powering processor and communication systems that require high levels of timing accuracy. Additionally, the device is compliant with IEC 62103 safety standards, demonstrating its commitment to quality and reliability.
