The LMK00338 is a low jitter, low noise clock generator designed for use in high speed clock generation and synchronization applications. It is a low power and low noise device with a wide operating temperature range. This versatile device offers several features, including Gigabit Ethernet to Ethernet synchronization, low latency interconnect, fast clock switching, and an adjustable output frequency range.
The LMK00338 is an integrated single-chip solution for generating, distributing, and synchronizing low-jitter clock signals. It is also an optimal choice for signal synchronization applications when low latency and jitter performance are required. The device integrates several functional blocks such as PLL, Voltage Controlled Oscillator, Amplifier, and programmable divider.
The LMK00338 is designed to generate low-jitter, low-noise clocks for communications applications in which synchronization and timing are key performance criteria. The device can be used for wide-range frequency for Ethernet communication systems and timing applications. It is designed to integrate seamlessly with Gigabit Ethernet and other interconnect systems that require an adjustable output frequency range, fast clock switching, and low latency. Additionally, the device can be configured to sync to multiple clock sources, including an existing Clock Synthesizer, Motherboard Clock Sources, or dedicated external clock sources through an input reference path.
The LMK00338 can operate up to a maximum clock frequency of 2.5GHz and has a frequency-adjustable range from 1 MHz to 2.5 GHz. The device uses a phase-locked loop (PLL) frequency synthesizer to generate low-jitter, low-noise clocks, and includes an adjustable, programmable divider that is used to generate specific desired frequencies. The device can generate clock frequencies up to 10 times faster than traditional clock sources, allowing for quick and efficient synchronization processing. The device is also capable of supporting fast clock switching between two clock sources.
The LMK00338 also integrates clean clock outputs, low-noise supplies, and internal bias circuitry that allow it to support different voltage levels, making it suitable for a range of applications. The device has a wide operating temperature range from -40°C to 125°C, which ensures robust and reliable operation in both extreme hot and cold environments. The LMK00338 also has excellent power efficiency for low power consumption in high-end applications.
In conclusion, the LMK00338 is an excellent choice for applications in which synchronisation and timing are critical. It is ideal for applications where high frequency and low latency are required, such as in Gigabit Ethernet or other interconnect systems. The device offers excellent performance, low noise, and power consumption in a wide temperature range and can generate multiple frequencies that can be controlled by an external signal or by internal programming.
