CY22313ZXC

Product Overview

The CY22313ZXC from Cypress Semiconductor Corp is an application-specific clock/timing IC for Direct Rambus clock generation in memory and RDRAM systems.The device includes a PLL and provides a 1:4 input-to-output ratio, with a maximum output frequency of 393.216MHz. It operates from a 3.15V to 3.6V supply and is rated for 0°C to 70°C. The IC is supplied in a surface-mount 24-TSSOP package with a 4.40 mm body width.

• Providing PLL-derived clock signals for memory-oriented electronic assemblies

Design & Procurement Notes

When selecting the CY22313ZXC, confirm that the board uses a 3.15V to 3.6V supply and that the required timing can be met with a 1:4 input-to-output ratio and a maximum output frequency of 393.216MHz. Because the differential input and output configuration is No/No, verify that the clocking scheme matches this No/No configuration. Check the 0°C to 70°C operating temperature range against the expected environment. The surface-mount 24-TSSOP package requires footprint and assembly compatibility. Since the supplied product status is Obsolete, procurement planning should account for lifecycle risk and verify the exact manufacturer part number.
