Detailed Description for SI5344A-D-GM
Product Overview
The Skyworks Solutions Inc. SI5344A-D-GM is a surface-mount clock generation device intended for frequency synthesis and phase-locked loop operation in electronic systems. It is offered in a 44-VFQFN package with an exposed pad and supports a supply voltage range of 1.71V to 3.47V across an operating temperature range of -40°C to 85°C. The device accepts LVCMOS, LVDS, LVPECL, and crystal inputs, and provides CML, HCSL, LVCMOS, LVDS, and LVPECL outputs. It is specified for a maximum frequency of 1.028GHz and includes one circuit with a 5:4 input-to-output ratio, supporting differential input and differential output configurations.
Key Features
- PLL-based clock generation with one circuit and a 5:4 input-to-output ratio.
- Input options include LVCMOS, LVDS, LVPECL, and crystal.
- Output options include CML, HCSL, LVCMOS, LVDS, and LVPECL.
- Maximum specified frequency is 1.028GHz.
- Differential input and differential output support is specified.
- Operates from a 1.71V to 3.47V supply.
- Surface-mount 44-VFQFN package with exposed pad.
Applications
- Generating synchronized timing signals for digital systems that require selectable output standards.
- Synthesizing reference frequencies for circuit blocks operating below the specified 1.028GHz maximum.
- Distributing clock signals to devices with LVCMOS, LVDS, LVPECL, CML, or HCSL input requirements.
- Using crystal or differential input sources to provide timing for board-level digital subsystems.
Design & Procurement Notes
Design and procurement considerations should focus on matching the selected input and output standards to the host circuitry, since the device supports multiple electrical formats rather than a single fixed interface. The 1.71V to 3.47V supply range and -40°C to 85°C operating range should be checked against the board power and ambient environment. The 44-VFQFN exposed-pad package requires surface-mount layout and appropriate pad handling for the final assembly. The 5:4 input-to-output ratio and 1.028GHz maximum frequency should be used to verify that the desired clock plan remains within the specified operating envelope.
