NB3V1102CDTR2G

Clock Buffers, Drivers Overview

The NB3V1102CDTR2G is a low skew fanout buffer from the NB3V110xC series, designed for LVCMOS clock distribution. It provides one input to two outputs with asynchronous output enable control. The device supports supply voltages of 3.3 V, 2.5 V, and 1.8 V, operating within a temperature range of -40°C to 105°C. Maximum input frequencies are 250 MHz at 3.3 V, 180 MHz at 2.5 V, and 133 MHz at 1.8 V. Propagation delay ranges from 0.8 ns to 3.5 ns depending on voltage. Output-to-output skew is less than 50 ps, and additive jitter is under 200 fs.

Clock Buffers, Drivers Feature Summary

• Low skew performance with output-to-output skew < 50 ps
• Very low additive jitter < 200 fs rms
• Asynchronous output enable (OE) control switches outputs to low state when OE is low
• Supports 3.3 V, 2.5 V, and 1.8 V LVCMOS environments

Clock Buffers, Drivers Applications

• LVCMOS clock distribution in high-performance systems
• Timing synchronization in modular electronic designs
• General purpose clock buffering requiring low skew and jitter

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DT' corresponds to the TSSOP-8 package and tape & reel shipping method. Confirm RoHS compliance and lead-free status as indicated by the 'G' suffix. Ensure the specific variant matches the required fan-out configuration, as other family members offer different output counts.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring a 1:2 LVCMOS fanout buffer. Choose based on the target supply voltage, as maximum frequency decreases at lower voltages (250 MHz at 3.3 V vs. 133 MHz at 1.8 V). Verify that the TSSOP-8 package fits the PCB layout constraints and that the thermal resistance characteristics are suitable for the operating environment.

Clock Buffers, Drivers Part Context

This part belongs to the NB3V110xC family, which includes 1:2, 1:3, 1:4, 1:6, and 1:8 variations. All family members share pin compatibility for easy handling and similar high-performance characteristics like low additive jitter and wide operating temperature range. The NB3V1102C specifically provides two outputs.

Clock Buffers, Drivers Replacement Considerations

Other devices in the NB3V110xC family such as NB3V1103C, NB3V1104C, NB3V1106C, and NB3V1108C are pin-compatible alternatives offering different fan-out ratios. Direct substitution requires verifying that the additional or fewer outputs do not impact the circuit design.
