86004BGLFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The 86004BGLFT is a high-performance 1:4 LVCMOS/LVTTL zero-delay clock buffer manufactured by Integrated Device Technology, now part of Renesas Electronics. It features a fully integrated PLL with an external feedback loop to achieve zero delay between input and output clocks. The device supports input and output frequencies from 15.625 MHz to 62.5 MHz, with a VCO operating range of 250 MHz to 500 MHz. It operates on single or mixed supply voltages (3.3V core/2.5V output) and provides four LVCMOS/LVTTL outputs with a typical 7Ω impedance. Key electrical parameters include a maximum cycle-to-cycle jitter of 65 ps and a maximum output skew of 65 ps.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero-delay clock regeneration using external feedback for precise phase alignment
• Integrated PLL with bypass mode via PLL_SEL pin for system testing
• Supports mixed voltage operation: 3.3V core/analog with 2.5V output
• Four LVCMOS/LVTTL outputs with configurable frequency division via F_SEL

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock distribution in digital systems requiring low skew
• Buffering LVCMOS/LVTTL reference clocks for multiple loads
• System test and debug configurations using PLL bypass mode

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging, distinct from the tube-packaged '86004BGLF'. Confirm RoHS compliance as indicated by the 'LF' suffix. Ensure the design accommodates the 16-lead TSSOP package dimensions and thermal requirements specified in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when zero-delay buffering of LVCMOS/LVTTL signals up to 62.5 MHz is required. Use the F_SEL pin to configure frequency ranges (15.625–31.25 MHz or 31.25–62.5 MHz). Consider the mixed-voltage capability if the system requires 3.3V logic levels internally but 2.5V output drivers.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 86004 series was originally produced by Integrated Device Technology (IDT). Following IDT's acquisition by Renesas Electronics, these products are managed under Renesas. The 86004BGLFT specifically denotes the lead-free, tape-and-reel version of the standard 86004 zero-delay buffer.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The 86004BGLF is the identical functional component packaged in a tube instead of tape and reel. No other direct substitutes are documented in the provided source material.
