SI53342-B-GM

Clock Buffers, Drivers Overview

The SI53342-B-GM is a low-jitter LVDS fanout clock buffer from the Si5334x family, manufactured by Skyworks Solutions Inc. It features a universal any-format input stage supporting LVPECL, LVDS, CML, HCSL, and LVCMOS signals via a 2:1 input multiplexer. The device provides six differential LVDS outputs organized into two independent banks (Bank A: Q0-Q2; Bank B: Q3-Q5), each with individual output enable control. Operating over a frequency range of dc to 1250 MHz, it delivers typical ultra-low additive jitter of 50 fs rms. Built-in LDOs ensure high power supply noise rejection, simplifying design in noisy environments. The component is housed in a 24-QFN package.

Clock Buffers, Drivers Feature Summary

• Universal any-format input compatibility with built-in 2:1 mux for CLK0/CLK1 selection
• Six LVDS outputs split across two independently controllable banks (Q0-Q2, Q3-Q5)
• Ultra-low additive jitter performance with typical value of 50 fs rms
• Integrated LDOs for enhanced power supply noise rejection (PSRR)

Clock Buffers, Drivers Applications

• Clock distribution networks requiring redundant clocking sources
• High-speed data acquisition systems needing precise timing alignment
• Telecommunications infrastructure utilizing multi-bank clock buffering

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and electrical specifications. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the source document explicitly identifies the manufacturer as Skyworks Solutions Inc. rather than a distributor or third-party reseller.

Clock Buffers, Drivers Selection Notes

Select this part when an application requires buffering up to six LVDS clocks from diverse input formats within a single package. The dual-bank architecture allows for independent power management and enable control of output groups. Verify that the required operating frequency does not exceed 1250 MHz and that the input signal slew rate meets the minimum requirements to maintain specified jitter performance.

Clock Buffers, Drivers Part Context

This component belongs to the Si53340-45 family of low-jitter LVDS fanout buffers. While other members like the SI53340 offer four outputs and the SI53344 offers ten, the SI53342 specifically provides a six-output configuration with dual-bank independence. All devices in this series share similar core technologies, including universal inputs and built-in LDOs, but differ in pin count and output capacity.
