NB2308AC1DTG

Overview

The NB2308AC1DTG is a commercial-grade, 3.3 V zero delay clock buffer manufactured by onsemi. It features an integrated PLL that locks to a reference clock input and distributes the signal across eight outputs organized into two banks of four. The device supports frequencies from 15 MHz to 133.3 MHz with a supply voltage range of 3.0 V to 3.6 V. Key electrical specifications include an input-to-output propagation delay under 250 ps, output-to-output skew less than 200 ps, and cycle-to-cycle jitter below 200 ps at 66.67 MHz. It utilizes advanced 0.35 µm CMOS technology and is housed in a TSSOP-16 package.

Feature Summary

• Zero Delay Buffer: Input-to-output propagation delay is adjustable via capacitive load on the feedback pin to achieve near-zero latency.
• Low Skew Performance: Guarantees output-to-output skew of less than 200 ps within the same bank.
• Configurable Output Banks: Two banks of four outputs each can be controlled independently via select inputs for three-stating or direct bypass modes.
• Wide Frequency Range: Supports input frequencies from 15 MHz up to 133.3 MHz.

Applications

• High-speed clock distribution in computing systems.
• Synchronization of multiple components requiring low-skew clock signals.
• System testing applications utilizing direct input-to-output bypass mode.

Procurement Notes

Verify the specific suffix 'DTG' confirms the TSSOP-16 package and Pb-Free status. Confirm the 'C' designation indicates the Commercial temperature range (0°C to 70°C). Ensure the ordering information matches the required shipping quantity, such as rail or tape & reel formats, as listed in the manufacturer's documentation.

Selection Notes

Select this component when a single-supply 3.3 V zero delay buffer is required for commercial temperature environments. The NB2308AC1 variant provides reference frequency outputs on both banks. Consider the NB2308AC1H if higher drive strength and faster rise/fall times are necessary for the application loads.

Part Context

This part belongs to the NB2308A family of zero delay buffers. The 'C' suffix denotes the commercial operating temperature range, while 'I' would indicate industrial range. The '1' specifies the configuration where both output banks provide reference frequency outputs. The 'DTG' suffix identifies the TSSOP-16 package with lead-free construction.

Replacement Considerations

For equivalent functionality, consider the NB2308AI1DTG for industrial temperature ranges or the NB2308AC1HDG for SOIC-16 packaging. Higher drive versions like NB2308AC1HDTG offer improved slew rates but maintain the same logical configuration.
