CY26580KOI-2T

Product Overview

CY26580KOI-2T from Cypress Semiconductor Corp is a PacketClock surface-mount clock IC that combines clock generation, fanout distribution, and multiplexing in a single circuit. The device accepts a CMOS input and provides a clock output with a specified 1:2 input-to-output ratio, supporting a maximum frequency of 133.33MHz. It includes a PLL with bypass and is offered in a 20-QSOP / 20-SSOP package with a 3.90mm width. The supply voltage range is 3.14V to 3.47V, and the operating temperature range is -40°C to 85°C.

Key Features

• Type: clock generator, fanout distribution, and multiplexer in one circuit.
• Input: CMOS; Output: clock; Differential input/output: no/no.
• Ratio: 1:2 input-to-output; Divider: yes; Multiplier: no.
• Maximum frequency: 133.33MHz.
• PLL: yes with bypass.
• Supply: 3.14V to 3.47V; Operating temperature: -40°C to 85°C.
• Package: 20-QSOP / 20-SSOP, 3.90mm width, surface mount.

Applications

• Clock distribution for single-board systems that require a CMOS clock input and a 133.33MHz maximum frequency.
• Fanout and multiplexing paths in designs using a 1:2 input-to-output ratio and PLL bypass behavior.
• Surface-mount timing blocks in compact designs using a 20-QSOP / 20-SSOP footprint and 3.14V to 3.47V supply.

Design & Procurement Notes

Design notes should focus on matching the supply rail to the 3.14V to 3.47V range and confirming that the board uses non-differential CMOS input and clock output interfaces. The 1:2 ratio, divider and no-multiplier configuration, and PLL bypass capability should be evaluated against the required clock topology. For layout and procurement, verify the exact 20-QSOP / 20-SSOP footprint, 3.90mm width, surface-mount package, and 133.33MHz maximum frequency, along with the -40°C to 85°C operating range.
