SL23EP04NZZC-1T

Clock Buffers, Drivers Overview

The SL23EP04NZZC-1T is a low skew, low jitter fanout clock buffer manufactured by Silicon Laboratories Inc. It converts one reference input clock into four buffered outputs, supporting frequencies from DC to 220 MHz with up to 30pF load capacitance. The device operates on a 3.3V or 2.5V supply and features an Output Enable (OE) control function. At 66MHz, typical power dissipation is 10mA at 3.3V and 9mA at 2.5V. It utilizes an internal voltage regulator for stable performance and is housed in an 8-pin TSSOP package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the exact shipping format and temperature grade. The 'T' suffix indicates tape and reel packaging, while 'Z' denotes lead-free compliance. Confirm that the OE logic configuration matches the system requirements, as variants exist with different enable behaviors.

Clock Buffers, Drivers Selection Notes

Select based on required operating temperature and load capacitance. The C-grade supports 0°C to 70°C, while I-grade covers -40°C to 85°C. Ensure the design accounts for the maximum load capacitance limits (15pF or 30pF) to maintain specified frequency ranges and skew parameters. Verify the OE logic state table aligns with the system's power-up and shutdown sequences.

Clock Buffers, Drivers Part Context

This component belongs to the SL23EP04NZ series of low skew clock buffers. The SL23EP04NZZC-1T specifically represents the commercial grade variant packaged in tape and reel. It shares core electrical characteristics with other members of the family but differs in OE logic implementation and environmental ratings compared to industrial grades or tube-packaged versions.
