CY2VC521ZXC-2

Product Overview

The CY2VC521ZXC-2 from Cypress Semiconductor Corp is a surface-mount zero delay buffer IC that accepts a crystal input and provides an LVDS differential output. It includes a PLL and supports a maximum frequency of 216MHz with a 1:1 input-to-output ratio. The device is housed in a 16-TSSOP package with a 0.173 in, 4.40 mm width and operates from a 3.15V to 3.45V supply over a 0°C to 70°C temperature range.

Key Features

• Zero delay buffer IC with PLL and one circuit
• Crystal input with LVDS differential output
• Maximum frequency of 216MHz
• 1:1 input-to-output ratio
• 3.15V to 3.45V supply voltage range
• 0°C to 70°C operating temperature range
• 16-TSSOP surface-mount package, 0.173 in, 4.40 mm width

Applications

• Buffering a crystal clock source for downstream LVDS loads in timing circuits
• Surface-mount clock paths that require an LVDS output at frequencies up to 216MHz
• Electronic assemblies operating within a 0°C to 70°C temperature range and using a 3.15V to 3.45V clock buffer supply

Design & Procurement Notes

When selecting this part, verify that the crystal input, single LVDS differential output, 216MHz maximum frequency, and 1:1 input-to-output ratio fit the clock architecture. The 3.15V to 3.45V supply range and 0°C to 70°C operating range should be matched to the board power and environmental conditions. The 16-TSSOP surface-mount package, 0.173 in, 4.40 mm width, affects land pattern, routing density, and clearance, while the differential output should be routed as a matched pair where appropriate.
