CSPT857CPAG8

Application Specific Clock/Timing Overview

The CSPT857CPAG8 is a zero-delay buffer and clock driver manufactured by Renesas Electronics Corporation. Designed for memory, DDR, and SDRAM applications, it features a single circuit with a 1:10 input-to-output ratio. The device supports differential inputs and outputs, operating at a maximum frequency of 220MHz. It requires a supply voltage between 2.3V and 2.7V and functions within an operating temperature range of 0°C to 70°C. The component is housed in a 48-TSSOP surface-mount package.

Application Specific Clock/Timing Feature Summary

• Integrated PLL for zero-delay buffering
• Differential input and output signaling
• 1:10 clock distribution ratio
• Maximum frequency of 220MHz

Application Specific Clock/Timing Applications

• Memory systems
• DDR interfaces
• SDRAM circuits

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix 'G8' against official Renesas documentation to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with the required 48-TSSOP footprint and check for any RoHS compliance certifications relevant to the manufacturing batch before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when a low-skew, zero-delay buffer is required for DDR or SDRAM clock distribution. Confirm that the system operates within the 2.3V to 2.7V supply range and the 0°C to 70°C temperature window. Verify that the 1:10 fan-out capability meets the design requirements for the target memory architecture.

Application Specific Clock/Timing Part Context

This part belongs to the CSPT857 series of clock buffers. Variants such as CSPT857DPAG and CSPT857CNLG8 share similar electrical characteristics but differ in package types like TFSOP or VFQFN. The CSPT857CPAG8 specifically utilizes the 48-TSSOP package configuration.
