Detailed Description for CY2077FZXI
Product Overview
The Cypress Semiconductor Corp CY2077FZXI is a surface-mount clock generator IC intended for single-channel frequency generation tasks. It is offered in an 8-TSSOP package with a 0.173 inch, 4.40 mm body width and operates from 3.3 V or 5 V supplies across a -40°C to 85°C temperature range. The device accepts clock or crystal input and provides CMOS and TTL outputs, with a 1:1 input-to-output ratio and an internal PLL. The maximum frequency values are 100 MHz and 133 MHz, and divider and multiplier functions are available.
Key Features
- Single clock generator circuit with an integrated PLL.
- Input options include clock and crystal sources.
- Output logic families include CMOS and TTL.
- 1:1 input-to-output ratio with divider and multiplier capability.
- Maximum frequency values of 100 MHz and 133 MHz.
- Supply voltage options of 3.3 V and 5 V.
- Operating temperature range of -40°C to 85°C.
- Surface-mount 8-TSSOP package, 0.173 inch, 4.40 mm width.
Applications
- Clocking digital logic subsystems that accept CMOS or TTL timing signals.
- Deriving a timing reference from a crystal oscillator in 3.3 V or 5 V board designs.
- Applying divider or multiplier functions near the 100 MHz and 133 MHz maximum frequency points.
- Placing a surface-mount PLL timing source in compact clock distribution layouts.
Design & Procurement Notes
When selecting this device, confirm that the board can provide either a 3.3 V or 5 V supply and that the chosen input is a clock or crystal source compatible with the single-circuit PLL architecture. The 1:1 input-to-output ratio should be reviewed alongside the divider and multiplier options to ensure the desired output timing is achievable without assuming additional channel count. Because the outputs are CMOS and TTL, verify the logic-level compatibility of downstream components. The 8-TSSOP surface-mount format, 0.173 inch, and 4.40 mm width affect land pattern and thermal behavior, while the -40°C to 85°C operating range should be matched to the intended ambient conditions. The maximum frequency values of 100 MHz and 133 MHz should be treated as the relevant frequency boundaries for initial timing planning.
