CY7B995AC

Overview

The CY7B995AC is a single-circuit clock buffer from the RoboClock series, manufactured by Cypress Semiconductor Corp. It supports a maximum frequency of 200 MHz with a 1:8 input-to-output ratio. The device accepts LVCMOS or LVTTL inputs and provides LVTTL outputs. It operates on dual voltage supplies: 2.375V to 2.625V or 2.97V to 3.63V. Designed for surface mount applications, it is housed in a 44-TQFP package (10x10 mm) and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports 200 MHz clock frequencies
• 1:8 fanout distribution capability
• Dual voltage operation (2.5V/3.3V)
• LVCMOS/LVTTL compatible inputs

Applications

• High-speed synchronous system clock distribution
• Nested clock tree architectures
• Multi-phase PLL clock buffering

Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm the commercial temperature grade (0°C to 70°C) and bulk packaging status. Ensure the selected variant matches the required supply voltage range of either 2.375V–2.625V or 2.97V–3.63V for the target design.

Selection Notes

Select this component when a 1:8 fanout is required for LVCMOS/LVTTL signals at up to 200 MHz. Confirm that the system environment stays within the 0°C to 70°C commercial temperature range. Verify compatibility with the available 2.5V or 3.3V power rails before integration into the PCB layout.

Part Context

This part belongs to the RoboClock family of high-speed multi-phase PLL clock buffers. It serves as a fanout distribution IC designed to drive multiple loads while maintaining signal integrity in demanding synchronous systems.

Replacement Considerations

Check for pin-compatible alternatives within the same RoboClock series that offer industrial temperature ranges if environmental conditions exceed 70°C. Verify electrical parameters such as output skew and drive strength against current designs.
