CY28353OXC-2T

Clock Buffers, Drivers Overview

The CY28353OXC-2T is a differential clock buffer and driver manufactured by Silicon Laboratories (Skyworks Solutions Inc.). It functions as a zero-delay PLL clock distribution device, converting one differential input pair to six differential output pairs. Designed for 2.5V operation, it supports frequencies up to 170 MHz with cycle-to-cycle jitter of ±100 ps. The component features Spread Aware EMI reduction, individual output enable/disable via a two-line serial interface, and conforms to the DDRI specification. It is housed in a 28-pin SSOP package.

Clock Buffers, Drivers Feature Summary

• Zero-delay buffer architecture distributing one differential input to six differential outputs
• Spread Aware functionality for electromagnetic interference reduction
• Two-line serial bus interface for individual output power management
• Conforms to DDRI specification for double data rate synchronous DRAM applications

Clock Buffers, Drivers Applications

• Double data rate (DDR) synchronous DRAM clock distribution
• High-performance system clock buffering
• EMI-sensitive digital circuit designs

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape and reel packaging format specified in the manufacturer's ordering information. Confirm the 'XC' suffix indicates lead-free compliance and commercial temperature range (0°C to +70°C). Ensure the source document explicitly links these suffixes to the physical attributes before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew, zero-delay buffer is required for DDR memory interfaces. The device operates at 2.5V and supports frequencies up to 170 MHz. Consider the 28-pin SSOP package constraints and the need for external feedback connections between FBINT/FBINC and FBOUTT/FBOUTC pins to achieve zero delay performance.

Clock Buffers, Drivers Part Context
