NB2308AC2DTG

Overview

The NB2308AC2DTG is a commercial-grade, 3.3 V zero delay clock buffer manufactured by onsemi in a TSSOP-16 package. It features an internal PLL that locks to a reference clock input and provides eight buffered outputs divided into two banks of four. The device supports configurable frequency multiplication, allowing users to obtain 2X and 1X frequencies on each output bank depending on the feedback connection. Key electrical specifications include a maximum operating frequency of 133 MHz, supply voltage range of 3.0 V to 3.6 V, and guaranteed output-to-output skew of less than 400 ps between banks.

Feature Summary

• Zero Delay Buffer with internal PLL for low-skew clock distribution
• Configurable frequency multiplication (2X and 1X) via feedback selection
• Two independent banks of four outputs with three-state control
• Commercial temperature range operation (-40°C to 85°C)
• TSSOP-16 surface-mount package

Applications

• High-speed clock distribution networks
• System synchronization in multi-device architectures
• Frequency multiplication in digital logic systems

Procurement Notes

Verify the ordering suffix 'DTG' corresponds to the TSSOP-16 package and Pb-Free status as defined in the manufacturer's ordering table. Confirm the 'C' suffix indicates the commercial temperature grade. Ensure design compatibility with the specific NB2308Ax2 configuration requirements regarding feedback pin connections.

Selection Notes

Select this part when a 2X/1X frequency split is required across two output banks. Compare against NB2308AC1 variants if reference frequency only is needed, or NB2308AC4 variants if uniform 2X multiplication is preferred. Verify load capacitance requirements (15 pF for >100 MHz) to ensure timing specifications are met.

Part Context

This component belongs to the NB2308A family of 3.3 V zero delay buffers. The 'C2' designation specifically identifies the NB2308AC2 variant, which enables distinct 2X and 1X frequency outputs based on feedback routing. The 'DTG' suffix denotes the TSSOP-16 package form factor with lead-free construction.

Replacement Considerations

NB2308AC2D (SOIC-16 package), NB2308AC2DR2G (Tape & Reel TSSOP-16). Functional equivalents from other manufacturers may require verification of pinout and electrical characteristics.
