Renesas Electronics Corporation Clock/Timing - Application Specific ICS9EX21501AKILF

The ICS9EX21501AKILF is a 15-output differential buffer designed for PCIe Gen2 (100MHz) and QPI (133MHz) applications. It features a 2:1 input multiplexer that allows for the selection between local and remote clock sources. The device can operate in fanout mode, providing output frequencies up to 400MHz. Key specifications include a cycle-to-cycle jitter of less than 50ps and output-to-output skew of less than 150ps, ensuring high signal integrity. The buffer supports zero delay and fanout modes, with selectable PLL bandwidths ranging from 80-150 MHz in PLL mode and 33-400 MHz in bypass mode. It includes 15 differential output pairs with a 0.7V current-mode output, making it suitable for a variety of applications. The device also features multiple SMBus addresses for flexibility in multi-device configurations and dedicated pins for power management, facilitating easier board design. The ICS9EX21501AKILF is available in a 64-pin MLF package and operates within a temperature range of -40 to +85°C.
