CY2XP21ZXC

Product Overview

The Cypress Semiconductor Corp CY2XP21ZXC is a clock generator IC packaged in an 8-TSSOP surface-mount case with a 4.40mm body width. It accepts a crystal input and provides an LVPECL differential output, with a maximum frequency of 140MHz. The device includes a PLL, contains one circuit, and uses a 1:1 input-to-output ratio. Supply voltage options are 2.375V to 2.625V or 3.135V to 3.465V, and the operating temperature range is 0°C to 70°C (TA).

Key Features

• Clock generator IC with an integrated PLL.
• Crystal input and LVPECL differential output.
• Maximum frequency of 140MHz.
• One circuit with a 1:1 input-to-output ratio.
• Non-differential input and differential output.
• Supply voltage ranges of 2.375V to 2.625V or 3.135V to 3.465V.
• Operating temperature range of 0°C to 70°C (TA).
• 8-TSSOP surface-mount package with 0.173in (4.40mm) width.

Applications

• Crystal-referenced clocking for digital logic boards that require an LVPECL output.
• Timing reference generation in measurement or control equipment operating within the 0°C to 70°C temperature range.
• Data acquisition systems that require a crystal-derived LVPECL clock output up to 140MHz.

Design & Procurement Notes

When selecting CY2XP21ZXC, verify that the board power supply is within one of the two permitted voltage ranges and that the thermal design keeps the ambient temperature within 0°C to 70°C (TA). The crystal input and LVPECL differential output should be matched to the rest of the timing chain, including appropriate layout and termination practices for differential signaling. The 8-TSSOP surface-mount package requires footprint compatibility with the intended assembly process and board density.
