CY25823ZZC

Product Overview

The CY25823ZZC from Cypress Semiconductor Corp is a surface-mount clock and frequency synthesizer designed for single-circuit clock generation, fanout distribution, and spread spectrum clock applications. It integrates a PLL, accepts an LVTTL input, and provides clock outputs with a 1:2 input-to-output ratio. The device supports a maximum frequency of 100 MHz and operates from a 3.135 V to 3.465 V supply in a 16-TSSOP package (0.173", 4.40 mm width).

Key Features

• Clock/Frequency Synthesizer with PLL, fanout distribution, and spread spectrum clock generator functionality.
• LVTTL input with differential clock output and 1:2 input-to-output ratio.
• Maximum frequency of 100 MHz in a single-circuit configuration.
• Supply voltage range of 3.135 V to 3.465 V.
• Operating temperature range of 0°C to 70°C.
• Surface-mount 16-TSSOP package, 4.40 mm width.

Applications

• Clock generation and distribution in embedded systems and board-level timing architectures.
• Fanout clock distribution where one input clock feeds multiple downstream logic or interface blocks.
• Spread spectrum clocking in clocked logic subsystems.

Design & Procurement Notes

For layout, verify that the system supply remains within the 3.135 V to 3.465 V range and that the input clock is compatible with LVTTL logic levels. The 1:2 input-to-output ratio and 100 MHz maximum frequency should be checked against the target timing budget. The differential output configuration should be considered when planning board routing and signal pairing. The 0°C to 70°C operating range and 16-TSSOP surface-mount package should be considered when selecting the PCB footprint, thermal path, and enclosure environment.
