NB3V1103CDTR2G

Clock Buffers, Drivers Overview

The NB3V1103CDTR2G is a 3.3 V LVCMOS low skew fanout buffer from the NB3V110xC series, manufactured by onsemi. It provides a 1:3 clock distribution with three outputs (Q0, Q1, Q2) in an 8-pin TSSOP package. The device supports asynchronous output enable control and operates within a supply voltage range of 3.0 V to 3.6 V at frequencies up to 250 MHz. Key electrical characteristics include a maximum propagation delay of 2.0 ns, output-to-output skew under 50 ps, and additive jitter below 200 fs. It functions across an extended temperature range of –40°C to +105°C.

Clock Buffers, Drivers Feature Summary

• Provides 1:3 LVCMOS clock fan-out with asynchronous OE control
• Very low output-to-output skew (< 50 ps) and additive jitter (< 200 fs)
• Supports 3.3 V, 2.5 V, and 1.8 V supply voltages
• Characterized for operation from –40°C to +105°C

Clock Buffers, Drivers Applications

• Clock distribution in high-performance digital systems
• Low skew buffering for LVCMOS logic interfaces
• Timing synchronization in modular electronic designs

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DT' corresponds to the TSSOP-8 package and 'R2G' indicates tape and reel shipping configuration. Confirm RoHS compliance and lead-free status as specified in the datasheet attributes. Ensure the application environment stays within the recommended operating conditions for VDD and temperature to maintain specified performance metrics.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:3 fan-out ratio is required for LVCMOS signals. Compare against NB3V1102C (1:2) or NB3V1104C (1:4) if different output counts are needed, noting their pin compatibility. Consider the 250 MHz maximum frequency limit at 3.3 V operation. Verify that the required skew and jitter specifications align with the device's < 50 ps skew and < 200 fs jitter capabilities.

Clock Buffers, Drivers Part Context

This part belongs to the NB3V110xC family of modular LVCMOS clock buffers. Family members including NB3V1102C, NB3V1104C, NB3V1106C, and NB3V1108C share similar high-performance characteristics and are designed for easy handling due to pin compatibility across variations.

Clock Buffers, Drivers Replacement Considerations

NB3V1102CDTR2G offers 1:2 fan-out; NB3V1104CDTR2G offers 1:4 fan-out. Both are pin-compatible alternatives within the same family.
