PCKV857DGG,512

Overview

The PCKV857DGG,512 is a differential clock driver and distribution IC designed for DDR SDRAM applications. It operates within a frequency range of 70 MHz to 190 MHz with a 1:10 output ratio. The device features an integrated PLL and supports SSTL-2 signaling standards. It requires a supply voltage (AVDD) between 2.2 V and 2.7 V and operates at temperatures from 0 °C to +70 °C. Housed in a 48-TSSOP package, it provides low skew and jitter performance suitable for high-speed memory interfaces.

Feature Summary

• Integrated PLL for clock generation and distribution
• 1-to-10 differential clock distribution capability
• Optimized for DDR SDRAM applications per JEDEC specifications
• Supports spread spectrum clocking for EMI reduction

Applications

• DDR SDRAM clock distribution
• High-speed memory interface circuits
• System-on-chip clock networks

Procurement Notes

Verify the specific ordering suffix '512' against official NXP documentation, as standard datasheets list 'PCKV857DGG'. Confirm RoHS compliance status and current production availability directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a differential 1:10 clock buffer with an internal PLL is required for DDR memory systems. Ensure the design accommodates the 2.3 V to 2.7 V VDDQ supply range and utilizes SSTL-2 compatible logic levels for inputs and outputs.

Part Context

This part belongs to the PCKV857 family of clock drivers manufactured by Philips/NXP Semiconductors. It is available in multiple packages including TSSOP, TVSOP, and VFBGA variants, all supporting the same core functionality for 70–190 MHz differential clock distribution.

Replacement Considerations

Check for updated revisions of the PCKV857 series. Verify pinout compatibility if substituting with other packages like PCKV857DGV (TVSOP) or PCKV857EV (VFBGA). No direct cross-model substitutes are listed in the provided data.
