8P34S2104NBGI8

Clock Buffers, Drivers Overview

The 8P34S2104NBGI8 is a dual 1:4 LVDS output fanout buffer manufactured by Renesas Electronics. It operates with a selectable 1.8V or 2.5V supply voltage and accepts LVDS, LVPECL, and single-ended LVCMOS input levels. The device features two independent buffer channels, each providing four low-skew outputs. Key electrical parameters include a maximum propagation delay of 300 ps, a maximum input clock frequency of 2.0 GHz, and typical output skew of 30 ps. It is housed in a 28-lead VFQFN package and supports an operating temperature range from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix NBGI8 against official Renesas documentation to confirm packaging details and RoHS compliance status. Ensure that the ordering suffix does not imply functional differences unless explicitly stated in the manufacturer's datasheet. Cross-reference the manufacturer part number with authorized distributor listings to confirm current production status and availability constraints.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring dual-channel LVDS fanout with matched AC characteristics between channels. The device is suitable for high-frequency clock distribution where low additive phase noise and high channel isolation are critical. Verify that the system power supply aligns with the 1.8V or 2.5V operational modes and that the input signal levels are compatible with LVDS, LVPECL, or LVCMOS standards.

Clock Buffers, Drivers Part Context

The 8P34S2104 belongs to the 8P34S210x series of high-performance, low-power differential fanout buffers. This series is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The device ensures guaranteed output-to-output and part-to-part skew characteristics, making it ideal for applications demanding well-defined performance and repeatability.

Clock Buffers, Drivers Replacement Considerations

The 8SLVD2104 is a similar dual 1:4 LVDS fanout buffer but operates exclusively on a 2.5V supply. When considering replacement, verify if the system design can accommodate the fixed 2.5V requirement, as the 8P34S2104 offers flexible 1.8V/2.5V operation.
