CY22391KLTFXC

Product Overview

The Cypress Semiconductor Corp CY22391KLTFXC is a surface-mount clock generator IC for 3.0 V to 3.6 V board-level timing designs. It uses a PLL and accepts a clock or crystal input to produce a clock output, with a maximum frequency of 166 MHz. The device provides divider and multiplier functions with a 1:8 input-to-output ratio and is supplied in a 32-VFQFN exposed-pad package with a 32-QFN (5x5) package outline.

Key Features

• Clock generator with PLL support for deriving a clock output from a clock or crystal input.
• Maximum frequency of 166 MHz with divider and multiplier operation.
• 1:8 input-to-output ratio specification.
• Single circuit with non-differential input and output.
• 3.0 V to 3.6 V supply voltage range.
• 32-VFQFN exposed-pad package, 32-QFN (5x5) package outline, surface mount.

Applications

• Embedded control boards that require a local timing source generated from a crystal or external clock reference.
• Single-ended clock distribution paths in digital logic subsystems operating within the 3.0 V to 3.6 V supply range.
• Frequency division or multiplication tasks where the generated clock remains within the 166 MHz maximum frequency.

Design & Procurement Notes

Confirm the exact manufacturer part number CY22391KLTFXC and the 32-QFN (5x5) package outline before layout. Verify that the design uses a single circuit and single-ended input/output interfaces, because the device is non-differential with one circuit. Check that the required frequency remains within 166 MHz and that the input-to-output relationship aligns with the 1:8 ratio specification. Match the 3.0 V to 3.6 V supply range and -10°C to 70°C operating temperature range to the target board environment. The exposed-pad package requires surface-mount assembly and pad handling appropriate to the PCB layout.
