NB3V1108CDTR2G

Clock Buffers, Drivers Overview

The NB3V1108CDTR2G is a low skew fanout buffer from the NB3V110xC family, manufactured by onsemi. It provides an 1:8 LVCMOS/LVTTL clock distribution with eight outputs in a TSSOP-16 package. The device supports supply voltages of 3.3 V, 2.5 V, and 1.8 V, with maximum operating frequencies of 250 MHz, 180 MHz, and 133 MHz respectively. Key electrical characteristics include a propagation delay of up to 3.5 ns at 1.8 V and output-to-output skew under 75 ps. It features asynchronous output enable control and operates within a temperature range of -40°C to +105°C.

Clock Buffers, Drivers Feature Summary

• Eight LVCMOS/LVTTL outputs providing 1:8 fan-out capability
• Very low output-to-output skew (< 75 ps) and additive jitter (< 200 fs)
• Asynchronous output enable (OE) control for switching outputs to a low state
• Wide operating voltage support: 3.3 V, 2.5 V, or 1.8 V

Clock Buffers, Drivers Applications

• Clock distribution in high-performance digital systems
• Buffering LVCMOS/LVTTL clock signals in communication equipment
• Timing synchronization in industrial control applications

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DT' corresponds to the TSSOP-16 package and 'R2G' indicates tape and reel packaging with lead-free compliance. Confirm RoHS status and Pb-Free marking via the manufacturer's documentation before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when an 8-channel LVCMOS/LVTTL clock buffer is required. Ensure the system voltage matches one of the supported levels (3.3 V, 2.5 V, or 1.8 V) as frequency limits vary accordingly. Verify that the TSSOP-16 package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the NB3V110xC modular family, which includes 1:2, 1:3, 1:4, 1:6, and 1:8 variations. All family members are pin-compatible, facilitating design upgrades or changes in fan-out requirements without altering the board layout.

Clock Buffers, Drivers Replacement Considerations

Other members of the NB3V110xC family (NB3V1102C, NB3V1103C, NB3V1104C, NB3V1106C) are pin-compatible alternatives if fewer outputs are sufficient.
