CY2077FZ

Product Overview

The CY2077FZ from Cypress Semiconductor Corp is a surface-mount clock generator integrated circuit in an 8-TSSOP package (0.173 in, 4.40 mm width). It is specified for a maximum frequency of 133 MHz and operates from a 3 V to 5.5 V supply over 0°C to 70°C ambient temperature. The device accepts clock or crystal inputs and provides CMOS or TTL outputs. It contains one circuit, has a 1:1 input-to-output ratio, and includes PLL and divider/multiplier functions. Differential input and output configurations are not supported.

Key Features

• Clock generator IC with integrated PLL.
• Accepts clock or crystal input and supports CMOS or TTL output formats.
• Maximum operating frequency is 133 MHz.
• Single circuit with a 1:1 input-to-output ratio.
• Divider and multiplier functions are supported.
• Supply voltage range is 3 V to 5.5 V.
• Rated for 0°C to 70°C ambient temperature operation.
• Surface-mount 8-TSSOP package, 0.173 in (4.40 mm) wide.
• Differential input and output operation is not supported.

Applications

• Clock distribution in embedded processing and control systems.
• Reference timing generation for digital logic and interface boards.
• Timing source generation for measurement and instrumentation equipment.
• Clock regeneration for crystal-referenced digital systems.

Design & Procurement Notes

Design planning should account for the 8-TSSOP surface-mount footprint, 4.40 mm package width, and the 3 V to 5.5 V supply range. The 0°C to 70°C ambient temperature rating should be checked against the final board environment. Because the device is specified as a single circuit with a 1:1 input-to-output ratio and non-differential input/output behavior, timing architectures should be planned around single-ended clock or crystal input and CMOS or TTL output stages. The 133 MHz maximum frequency, PLL, and divider/multiplier functions should be evaluated against target clock rates, input reference characteristics, and downstream logic requirements.
