ICS9250BF-12

Overview

The ICS9250BF-12 is a frequency timing generator manufactured by Renesas Electronics Corporation, designed for application-specific clock and timing requirements. It features a single PLL circuit with one crystal input and twenty-four clock outputs, providing a 1:24 output ratio without differential signaling capabilities. The device supports maximum frequencies up to 133MHz and operates on a supply voltage range of 3.135V to 3.465V. Packaged in a 56-BSSOP (56-SSOP) surface-mount case measuring 7.50mm in width, it functions within an operating temperature range of 0°C to 70°C.
