SI53365-B-GTR

Clock Buffers, Drivers Overview

The Skyworks Si53365-B-GTR is an LVCMOS fanout clock buffer featuring eight outputs and a frequency range from DC to 200 MHz. It utilizes advanced CMOS technology to provide low additive jitter (120 fs RMS typical), low skew, and low propagation delay variability. The device includes built-in LDOs for high PSRR performance, eliminating the need for external filtering components. It operates on a single supply voltage of 1.8 V, 2.5 V, or 3.3 V within the –40 °C to +85 °C temperature range.

Clock Buffers, Drivers Feature Summary

• Eight LVCMOS outputs with a maximum frequency of 200 MHz
• Low additive jitter: 120 fs RMS typical
• Built-in LDOs for high power supply rejection ratio (PSRR)
• Single-ended LVCMOS input with internal pull-up resistor

Clock Buffers, Drivers Applications

• Clock distribution in noisy environments
• Redundant clocking applications
• End-to-end clock tree performance with oscillators and jitter attenuators

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix '-B-GTR' against the manufacturer's current documentation to confirm package type and reel specifications. Confirm RoHS compliance status via the official Certificate of Conformance provided by Skyworks Solutions.

Clock Buffers, Drivers Selection Notes

Select the Si53365 when eight LVCMOS outputs are required without dual-bank configuration options available in other family members like the Si53362. Ensure the application supports single-ended inputs and does not require the dual-input MUX feature found in the Si53360/61 variants.

Clock Buffers, Drivers Part Context

The Si53365 belongs to the Si5336x family of low-jitter LVCMOS fanout buffers. This family also includes the Si53360, Si53361, and Si53362, which offer varying output counts and configurations such as dual banks or dual inputs.

Clock Buffers, Drivers Replacement Considerations

Si53360-B-GMR provides similar functionality but includes two clock inputs and a MUX option. Si53361-B-GMR offers eight outputs in a QFN package instead of TSSOP.
