SI53365-B-GT

Clock Buffers, Drivers Overview

The Skyworks Solutions Inc. Si53365-B-GT is a low-jitter, LVCMOS fanout clock buffer featuring eight outputs and a frequency range from DC to 200 MHz. Utilizing advanced CMOS technology, it guarantees low additive jitter of 120 fs RMS, low skew, and minimal propagation delay variability. The device integrates built-in LDOs for high PSRR performance, eliminating the need for external filtering components. It operates within an ambient temperature range of –40 °C to +85 °C and supports supply voltages of 1.8 V, 2.5 V, or 3.3 V.

Clock Buffers, Drivers Feature Summary

• Low additive jitter: 120 fs RMS (typical) with guaranteed maximums up to 250 fs depending on voltage and frequency.
• Built-in LDOs deliver high power supply rejection ratio (PSRR), simplifying design in noisy environments.
• Single-ended LVCMOS input driving eight LVCMOS outputs with configurable output enable control.
• Operates across a wide temperature range of –40 °C to +85 °C.

Clock Buffers, Drivers Applications

• Clock and data distribution systems requiring low jitter buffering.
• Redundant clocking applications utilizing single-ended inputs.
• End-to-end clock tree performance when paired with Skyworks oscillators or jitter attenuators.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix '-GT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status via the official Skyworks Certificate of Conformance before procurement.

Clock Buffers, Drivers Selection Notes

Select the Si53365 variant specifically for single-ended LVCMOS input requirements. Ensure the application does not require dual-input multiplexing, which is available in the Si53360/61/62 family. Validate that the load capacitance and slew rate requirements align with the AC characteristics defined in the electrical specifications table.

Clock Buffers, Drivers Part Context

The Si53365 belongs to the Si5336x family of fixed-format LVCMOS buffers. Unlike the Si53360/61/62 models, it features a single clock input rather than a dual-input MUX configuration. It provides eight outputs, whereas the Si53362 offers twelve outputs split into two banks.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical parameters if considering alternative manufacturers.

Clock Buffers, Drivers FAQ

Does the Si53365 support dual-input clock selection?

No, the Si53365 features a single clock input (CLK). Dual-input MUX functionality is available in the Si53360, Si53361, and Si53362 models.

What is the typical additive jitter performance?

The device guarantees a typical low additive jitter of 120 fs RMS, measured from 12 kHz to 20 MHz.

How should unused outputs be handled?

Unused outputs should be left unconnected to ensure proper operation and minimize noise coupling.
