IDT5V927PGGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The IDT5V927 is a low-cost, low-skew, low-jitter quad output clock generator designed for Gigabit Ethernet, Fibre Channel, and OC-3 applications. It operates on a 3V to 3.6V supply with an industrial temperature range of -40°C to +85°C. The device generates output frequencies from 50MHz to 160MHz using input frequencies between 6.25MHz and 80MHz. It features an internal RC filter eliminating external components, accepts fundamental mode crystals up to 40MHz, and includes selectable feedback divide ratios (2, 3, 4, 4.25, 5, 6, 6.25, 8) via S1/S0 pins.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Quad outputs generating 50MHz to 160MHz with cycle-cycle jitter under 200ps at 100MHz
• Internal PLL feedback loop and RC filter remove need for external components
• Selectable feedback divide ratios (2, 3, 4, 4.25, 5, 6, 6.25, 8) via S1/S0 pins
• Power-down mode draws less than 500μA when S1=H, S0=H

Clock Generators, PLLs, Frequency Synthesizers Applications

• Gigabit Ethernet systems
• Fibre Channel interfaces
• OC-3 networking equipment
• Network switches and routers
• Storage Area Networks (SAN)

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the package type matches the TSSOP configuration. Confirm the suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Ensure the crystal or input source meets the specified frequency and ESR requirements before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for designs requiring four synchronized clock outputs derived from a single reference. Verify that the required output frequency falls within the 50MHz to 160MHz range. Check if the specific feedback divide ratio needed is supported by the S1/S0 pin combinations listed in the datasheet.
