276PGILFT

Overview

The ICS276PGILFT is a triple PLL field-programmable VCXO clock synthesizer manufactured by Renesas Electronics Corporation under the VersaClock series. It generates up to three high-quality, high-frequency clock outputs from a low-frequency crystal input, designed to replace discrete crystals and oscillators. The device operates with a supply voltage of 3.135V to 3.465V and supports frequencies up to 200MHz. It features CMOS outputs and is available in a 16-TSSOP package. The component includes frequency division and multiplication capabilities within a single integrated circuit.

Feature Summary

• Triple PLL architecture generating up to three independent clock outputs
• Field-programmable configuration for flexible system integration
• Supports frequency division and multiplication functions
• Operates within -40°C to +85°C industrial temperature range

Applications

• Systems requiring replacement of discrete crystals and oscillators
• Applications needing multiple reference clocks from a single low-frequency input
• High-frequency clock distribution networks

Procurement Notes

Verify the manufacturer date code and lot number against the specific order requirements. Confirm that the 16-TSSOP package dimensions match the PCB footprint specifications. Ensure the supply voltage range of 3.135V to 3.465V aligns with the target system power rails before procurement.

Selection Notes

Select this component when a single crystal input must drive multiple high-frequency CMOS loads. The ICS276 eliminates the need for separate VCXOs and buffers. Verify that the required output frequencies fall within the 200MHz maximum limit and that the 1:3 input-to-output ratio suits the design topology.

Part Context

The ICS276 belongs to the VersaClock family of clock synthesizers. The suffix PGI indicates the 16-TSSOP package variant, while LFT denotes lead-free and RoHS compliance. This part integrates functionality typically provided by multiple discrete components, simplifying board layout and reducing component count in timing-critical applications.

Replacement Considerations

Direct pin-compatible replacements are not publicly confirmed for this specific part number. System redesign may be necessary if substituting with other VersaClock models due to differences in programmability and output configurations.
