8S89202BKILFT

Clock Buffers, Drivers Overview

The 8S89202BKILFT is a high-speed clock divider and distribution component manufactured by Renesas Electronics. It features a 2:1 LVPECL multiplexer with an internal 1:8 fanout buffer, designed for low skew applications. The device supports differential input levels including LVPECL, LVDS, and CML via internally terminated inputs. It offers selectable output dividers of ÷1, ÷2, and ÷4 across three output banks. Electrical specifications include a maximum output frequency of 1.5 GHz and a maximum input frequency of 3 GHz. It operates on a single supply voltage of 2.5V ±5% or 3.3V ±10%, with an operating temperature range from -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'T' corresponds to Tape & Reel packaging with EIA-481-C pin 1 orientation as specified in the datasheet. Confirm that the manufacturer designation aligns with Renesas Electronics following corporate acquisitions. Ensure the component meets lead-free (RoHS 6) requirements if applicable to the design constraints.

Clock Buffers, Drivers Selection Notes

Select this component when interfacing differential clocks such as LVDS or CML into an LVPECL distribution network. The internal 50Ω termination simplifies input matching. Verify that the required output frequency does not exceed 1.5 GHz. Ensure the power supply voltage matches either the 2.5V or 3.3V specification, as the device supports both ranges independently.

Clock Buffers, Drivers Part Context

This part belongs to the 8S8920x series of low skew clock solutions originally developed by Integrated Device Technology (IDT). The series is characterized by high-performance timing capabilities suitable for demanding serial communication standards. The 8S89202 specifically provides a 2:1 mux configuration, distinguishing it from variants with different mux ratios or fanout counts within the same family.
