Detailed Description for CY2XP21ZXI
Product Overview
The CY2XP21ZXI from Cypress Semiconductor Corp is a surface-mount clock generator IC supplied in an 8-TSSOP package. It accepts a crystal input and provides an LVPECL output. The maximum frequency is 140MHz. The device includes a PLL and operates from a 2.375V to 3.465V supply across an operating temperature range of -40°C to 85°C. Its package width is 0.173 inches, or 4.40 mm.
Key Features
- Clock generator type with integrated PLL
- Crystal input and LVPECL output
- One circuit with 1:1 input-to-output ratio
- Maximum frequency of 140MHz
- Non-differential input and differential output
- Operating supply voltage range of 2.375V to 3.465V
- Surface-mount 8-TSSOP package (0.173-inch, 4.40 mm width)
- Operating temperature range of -40°C to 85°C
- Mounting type: Surface Mount
Applications
- Board-level timing for equipment that requires a crystal-derived clock reference and a differential LVPECL output
- Embedded systems that use LVPECL clock inputs and operate within the specified voltage and temperature limits
- Compact surface-mount designs where an 8-TSSOP clock generator can fit within a 0.173-inch, 4.40 mm package outline
- Reference clock generation for circuits needing a 140MHz maximum frequency with a 1:1 input-to-output ratio
Design & Procurement Notes
Designers should verify that the PCB footprint matches the 8-TSSOP surface-mount package and that the system supply remains within 2.375V to 3.465V. The one-circuit, 1:1 input-to-output relationship should be considered when planning the clock tree, along with the non-differential crystal input and differential LVPECL output. The 140MHz maximum frequency and -40°C to 85°C operating range define the electrical and thermal boundaries for selection. Board layout should also account for the 0.173-inch, 4.40 mm package width when placing adjacent components.
