Renesas Electronics Corporation Application Specific Clock/Timing ICS557G-08T

The ICS557G-08T is a 2:1 multiplexer chip designed for PCI-Express applications, enabling the selection of one of two HCSL or LVDS input pairs to output a single pair of differential signals. It operates at a voltage of 3.3 V and supports input clock frequencies up to 200 MHz for HCSL and 100 MHz for LVDS. The device is packaged in a 16-pin TSSOP format and features low power consumption. It includes pins for power, ground, input signals, and control functions such as power down and output enable. Proper PCB layout and decoupling capacitor placement are recommended for optimal performance. The chip is suitable for applications requiring reliable clock signal multiplexing in high-speed data environments.
