The SL23EP09ZI-1H is a 1:9 zero delay clock buffer designed and manufactured by Silicon Labs. It is an industry standard clock buffer that provides high-performance timing synchronization between different clock domains. The device has an operating temperature range of -40°C to +125°C and requires a maximum supply voltage of 3.3V. It supports EMI suppression and has a maximum propagation delay of 12ns. The output can be enabled or disabled for further customization and the device has an integrated loop filter for maintaining low jitter and consistent signal integrity. Additionally, it has increased isolation for reduced crosstalk and improved signal-to-noise ratio.
