CA3254E

Product Overview

The Harris Corporation CA3254E is a through-hole clock generator IC for timing functions in electronic assemblies. It provides one PLL-based clock circuit with a crystal output and a 2:1 input-to-output ratio. The device supports divider operation, does not support multiplier operation, and uses non-differential input and output interfaces. It uses a 24-pin dual in-line package (24-PDIP) with a 0.300 in body width (7.62 mm), and it operates from a 7.5 V to 10.5 V supply over an ambient temperature range of 0°C to 70°C.

Key Features

• Clock generator IC with a phase-locked loop (PLL)
• Single circuit with crystal output
• Input-to-output ratio of 2:1
• Divider operation supported; multiplier operation not supported
• Non-differential input and output configuration
• 7.5 V to 10.5 V supply voltage range
• Operating temperature range of 0°C to 70°C (TA)
• Through-hole 24-PDIP package with 0.300 in (7.62 mm) body width

Applications

• Generating a derived clock signal for digital logic assemblies that require a crystal output and a 2:1 timing ratio
• Dividing a timing reference in synchronous circuits where a single PLL-based clock circuit is sufficient
• Implementing through-hole clock generation in equipment boards that use a 7.5 V to 10.5 V supply and operate at 0°C to 70°C ambient

Design & Procurement Notes

When selecting the CA3254E, confirm that the system timing plan accepts a non-differential, divider-only clock architecture with a 2:1 input-to-output ratio. The 7.5 V to 10.5 V supply range and 0°C to 70°C ambient operating range should be checked against the board power rail and enclosure conditions. Because the device uses a through-hole 24-PDIP package, PCB layout must reserve appropriate pin spacing and mechanical clearance for the 0.300 in (7.62 mm) package. These considerations help ensure that the single PLL-based clock circuit can be integrated without requiring multiplier functionality or differential signal paths.
