8S89202BKILF/W

Clock Buffers, Drivers Overview

The 8S89202BKILF/W is a high-speed clock divider and distribution component manufactured by Renesas Electronics Corporation, originally designed by Integrated Device Technology. It functions as a low skew 2:1 LVPECL multiplexer with a 1:8 fanout buffer and internal termination. The device accepts differential inputs in LVPECL, LVDS, or CML formats and provides eight LVPECL output pairs across three banks. It supports selectable output dividers of ÷1, ÷2, and ÷4, allowing multiple frequencies from a single reference. Key electrical parameters include a maximum input frequency of 3 GHz and a maximum output frequency of 1.5 GHz. The part operates on a 2.5V ±5% or 3.3V ±10% supply voltage within an ambient temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Three output banks providing eight total LVPECL differential output pairs with selectable ÷1, ÷2, and ÷4 division ratios.
• Internal 50Ω termination on IN/nIN inputs simplifies interfacing with LVPECL, LVDS, and CML signal families.
• Low skew performance with typical bank-to-bank skew of 6ps and additive phase jitter of 0.166ps RMS at 156.25MHz.
• Compact 32-lead VFQFN package (5mm x 5mm) with exposed thermal pad for efficient heat dissipation.

Clock Buffers, Drivers Applications

• SONET/SDH network infrastructure
• 1 Gigabit and 10 Gigabit Ethernet systems
• Fibre Channel storage area networks

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix when sourcing components. The '/W' suffix indicates tape and reel packaging with Pin 1 orientation defined by EIA-481-D. Ensure compatibility with the required operating voltage (2.5V or 3.3V) and confirm that the lead-free RoHS 6 compliance meets environmental standards for the target assembly process.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew clock distribution solution is required for high-speed serial links. The internal termination reduces external component count for LVDS/CML/LVPECL inputs. Consider the thermal resistance (θJA) of 42.7°C/W and implement adequate PCB thermal vias connected to ground to manage power dissipation, especially if all outputs are loaded simultaneously.

Clock Buffers, Drivers Part Context

This device belongs to the 8S89200 series of clock drivers and distributors. It was originally developed by Integrated Device Technology (IDT), which has since been acquired by Renesas Electronics Corporation. The product line continues to be supported under the Renesas portfolio, maintaining the original IDT specifications and pinouts for design continuity.

Clock Buffers, Drivers Replacement Considerations

The datasheet does not list direct cross-reference part numbers. Designers should evaluate other devices within the Renesas IDT clock distribution portfolio that offer similar 2:1 MUX functionality and 1:8 fanout capabilities with compatible LVPECL outputs and package dimensions.
