SL23EP04SI-2T

Clock Generators, PLLs, Frequency Synthesizers Overview

The SL23EP04SI-2T is a Zero Delay Buffer (ZDB) manufactured by Skyworks Solutions Inc. It operates within a frequency range of 10 to 220 MHz and provides four buffered clock outputs from a single reference input. The device supports a power supply voltage range of 2.5V to 3.3V, with typical current consumption of 10 mA at 66 MHz under 2.5V conditions. It features low output clock skew of 60 ps typ and cycle-to-cycle jitter up to 400 ps max. The component is housed in an 8-pin SOIC package and is rated for industrial operating temperatures between -40°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel shipping configuration rather than tube packaging. Confirm the '-SI-' designation aligns with the required industrial temperature grade (-40°C to +85°C). Cross-reference the manufacturer part number against current distributor listings to ensure availability and correct RoHS compliance status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low skew and low jitter are critical for high-speed clock distribution. Ensure the load capacitance requirements match the specified electrical characteristics for the desired frequency range. Verify that the standard drive level meets the impedance requirements of the connected loads compared to the high-drive option.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the SL23EP04 series of zero delay buffers designed for high-performance clock distribution. It is distinct from other variants by its specific drive strength and frequency capabilities defined by the ordering suffixes. The product line includes both commercial and industrial grades with varying drive options.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How does the FBK pin function within the circuit?

The FBK pin serves as the PLL feedback input and must be connected externally to one of the four clock outputs to allow the internal PLL to lock onto the reference clock.

What happens if the CLKIN input receives a DC signal?

If the CLKIN input is DC (GND to VDD), the device enters Power Down mode, tri-stating all four outputs and turning off the PLL to minimize power consumption.

Can the device handle spread spectrum clocking inputs?

Yes, the SpreadThru™ feature allows the device to pass modulated spread spectrum clock signals from the reference input to the outputs without degrading the spread percentage or profile.
