280PGLFT

Overview

The Renesas 280PGLFT is a VersaClock clock generator and frequency synthesizer housed in a 16-TSSOP package. It operates as a fanout distribution device with spread spectrum capabilities, supporting a maximum frequency of 200MHz. The IC accepts clock or crystal inputs and provides CMOS outputs. It functions within a supply voltage range of 3.135V to 3.465V and is rated for an operating temperature between 0°C and 70°C. This component belongs to the VersaClock series and includes a PLL with bypass functionality.

Feature Summary

• Integrated clock/frequency synthesizer with fanout distribution
• Supports spread spectrum clock generation
• CMOS output interface with 1:4 input-to-output ratio
• Operates on a single 3.3V nominal supply (3.135V–3.465V)

Applications

• General purpose clock distribution in embedded systems
• Spread spectrum clocking for EMI reduction
• Frequency synthesis for digital logic interfaces

Procurement Notes

Verify the 'LF' suffix indicates lead-free compliance and RoHS3 status. Confirm the 'T' suffix denotes tape-and-reel packaging rather than tube. Check current product status as the base model has been marked End-of-Life by the manufacturer. Ensure the specific revision matches design requirements before procurement.

Selection Notes

Select this part when a fixed-frequency 200MHz CMOS clock source with spread spectrum capability is required. Verify that the 16-TSSOP package fits the PCB layout constraints. Ensure the application does not require differential outputs, as this device provides single-ended CMOS signals only. Confirm the 0°C to 70°C industrial temperature range meets environmental specifications.

Part Context

The 280PGLFT is part of the ICS280 family from Renesas Electronics. It serves as a replacement for legacy clock generators requiring spread spectrum features. The device integrates a PLL and buffer stages into a single low-pin-count package, simplifying board design compared to discrete solutions.
