CY26049ZXC-36

Product Overview

The CY26049ZXC-36 from Cypress Semiconductor Corp is a surface-mount clock and frequency synthesis device intended for timing distribution and clock generation tasks in digital systems. It combines clock/frequency synthesizer, clock generator, fanout distribution, and jitter attenuation functions in a single 16-TSSOP package. The device accepts a clock input and provides clock outputs, with a 1:3 input-to-output ratio and a maximum frequency rating of 155MHz. A PLL with bypass is included, while the input and output interfaces are non-differential. The supply range is 3.15V to 3.45V, and the operating temperature range is 0°C to 70°C.

Key Features

• Integrated clock/frequency synthesizer, clock generator, fanout distribution, and jitter attenuator functions.
• PLL with bypass capability.
• Single circuit with clock input and clock output, using a 1:3 input-to-output ratio.
• Maximum frequency rating of 155MHz.
• Non-differential input and output interfaces.
• 3.15V to 3.45V supply range and 0°C to 70°C operating range.
• Surface-mount 16-TSSOP package, 0.173 inch / 4.40mm width.

Applications

• Clock distribution to several synchronous logic blocks on a PCB.
• Jitter attenuation in clock paths feeding synchronous digital subsystems.
• Clock regeneration for digital equipment requiring a common timing reference.

Design & Procurement Notes

For CY26049ZXC-36, check that the board uses non-differential clock input and output interfaces, as the device has non-differential input and output. Confirm that the timing architecture is compatible with the 1:3 input-to-output ratio and that all required clock signals remain within the 155MHz maximum frequency. The 3.15V to 3.45V supply range and 0°C to 70°C operating range should match the system power rail and ambient conditions. The surface-mount 16-TSSOP package, 0.173 inch / 4.40mm width, should be considered during footprint layout, soldering process selection, and mechanical clearance planning. Review manufacturer technical documentation for pin assignments, configuration, and detailed timing guidance.
