IDTCSPT857DNLG

Overview

The IDTCSPT857DNLG 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 40-VFQFN package with an exposed pad, specifically identified as a 40-VFQFPN (6x6) supplier device package.

Procurement Notes

Verify the specific ordering suffix against official Renesas documentation to confirm package type and temperature range. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement. Check current product lifecycle status, as availability may vary based on production schedules.

Selection Notes

Select this component when a low-skew, zero-delay buffer is required for DDR/SDRAM memory interfaces. Ensure the design accommodates the 2.3V to 2.7V supply voltage range. Verify that the 40-VFQFPN footprint matches the PCB layout requirements. Consider thermal management capabilities within the specified 0°C to 70°C operating range.

Part Context

This part belongs to the CSPT857 series of clock drivers from Renesas Electronics. The series includes variants such as CSPT857DPAG and CSPT857CNL8, which share similar electrical characteristics but differ in packaging options like TSSOP or other QFN configurations. The IDT prefix indicates its heritage from Integrated Device Technology prior to acquisition.
