This document is a product specification manual, which mainly introduces the characteristics of the product, such as operating frequency and clock frequency.
The ICS9148-11 is a frequency generator and integrated buffer designed for high-speed RISC or CISC microprocessor systems, such as Intel PentiumPro. It generates four processor clocks, six bus clocks, one 14.318MHz clock, and twelve SDRAM clocks with synchronous skew matching.
The device features power management capabilities controlled by the MODE pin, allowing for CPU_STOP#, PCI_STOP#, and PWR_DWN# functions. It includes a serial configuration interface via I2C protocol and is available in a 48-pin SSOP package.
The nominal voltage for the VDD(1:3) power supply is 3.3V.
The latency of Power Down will not be greater than 3ms.
The CPUCLKs will have a turn ON latency of at least 3 CPU clocks.
