CY28322ZC-2

Product Overview

The Cypress Semiconductor Corp CY28322ZC-2 is a surface-mount clock driver, clock synthesizer, and spread spectrum clock generator IC in a 48-TFSOP (0.240", 6.10mm Width) package. It has a single circuit, a Clock and LVTTL input, and a Clock output. The device provides a PLL with bypass, a 1:21 input-to-output ratio, and a maximum frequency of 14.318 MHz. Supply voltage ranges are 2.85 V to 3.465 V and 3.135 V to 3.465 V. The ambient operating temperature range is 0°C to 70°C.

Key Features

• Clock Driver, Clock Synthesizer, and Spread Spectrum Clock Generator functionality in a single circuit.
• PLL with bypass.
• Clock and LVTTL input options with a Clock output.
• 1:21 input-to-output ratio and 14.318 MHz maximum frequency.
• Non-differential input and output interface.
• Divider operation is supported; multiplier operation is not supported.
• 48-TFSOP (0.240", 6.10mm Width) package with 48-TSSOP package designation.
• 2.85 V to 3.465 V and 3.135 V to 3.465 V supply ranges.
• 0°C to 70°C ambient operating range.

Applications

• Clock generation and distribution in digital circuit boards with Clock and LVTTL input types.
• PLL timing reference conditioning in LVTTL clock input systems.
• Spread-spectrum clock generation in digital assemblies with a 14.318 MHz maximum clock frequency.

Design & Procurement Notes

Designers should verify the 48-TSSOP package designation, 48-TFSOP body dimensions, and 6.10 mm width during PCB layout and bill-of-material preparation. The two supply ranges, 2.85 V to 3.465 V and 3.135 V to 3.465 V, may require checking the selected rail against the board power tree. Because the input and output are non-differential, signal conditioning should match Clock and LVTTL levels. The 1:21 ratio, 14.318 MHz maximum frequency, PLL bypass, divider capability, and multiplier capability should be checked against the timing plan. The 0°C to 70°C ambient range should be compared with the expected thermal environment.
