CY26049ZXI-36

Product Overview

The CY26049ZXI-36 from Cypress Semiconductor Corp is a 16-TSSOP surface-mount clock and frequency synthesizer IC. It combines clock generation, fanout distribution, and jitter attenuation in a single circuit, with a clock input and clock output path. The device supports a maximum frequency of 155 MHz, uses a 1:3 input-to-output ratio, and includes a PLL with bypass. It operates from a 3.15 V to 3.45 V supply over a -40°C to 85°C temperature range, and the input and output interfaces are non-differential.

Key Features

• Clock generation, frequency synthesis, fanout distribution, and jitter attenuation are integrated in one circuit.
• PLL with bypass is available for clock path configuration.
• A 1:3 input-to-output ratio supports clock fanout applications.
• The input and output interfaces are non-differential.
• The maximum frequency is 155 MHz.
• Divider operation is supported, while multiplier operation is not included.
• Supply voltage range is 3.15 V to 3.45 V, with operation from -40°C to 85°C.
• The device uses a 16-TSSOP surface-mount package with 4.40 mm body width.

Applications

• Generating a primary clock reference for digital logic and timing circuits.
• Distributing a clock signal through a single circuit with a 1:3 input-to-output ratio.
• Reducing clock jitter before timing signals reach downstream circuitry.
• Providing compact clock fanout in surface-mount board layouts.

Design & Procurement Notes

When selecting the CY26049ZXI-36, verify that the board supply remains within the 3.15 V to 3.45 V range and that the ambient operating environment stays between -40°C and 85°C. The 16-TSSOP surface-mount package supports compact layouts, but the 4.40 mm body width should be checked against the footprint and nearby component spacing. Because the input and output interfaces are non-differential, clock routing should be planned around single-ended signal handling rather than differential pairs. The 1:3 input-to-output ratio, PLL with bypass, divider operation without multiplier operation, and 155 MHz maximum frequency should be considered during clock tree design to ensure compatibility with downstream timing requirements.
