Detailed Description for SI5340B-D-GM
Product Overview
The SI5340B-D-GM from Skyworks Solutions Inc. is a surface-mount clock and timing integrated circuit that combines jitter attenuation and multiplexing functions in a 44-VFQFN exposed-pad package. It supports a PLL, accepts LVCMOS, LVDS, LVPECL, and crystal inputs, and provides CML, HCSL, LVCMOS, LVDS, and LVPECL outputs. The device supports a maximum frequency of 350 MHz and a supply range of 1.71 V to 3.47 V, with operation from -40°C to 85°C. Its 4:4 input-to-output ratio and differential input/output capability support clock distribution architectures with multiple input sources and output formats.
Key Features
- Jitter attenuator and multiplexer function for clock and timing paths
- PLL included, with differential input and output support
- Input options include LVCMOS, LVDS, LVPECL, and crystal
- Output options include CML, HCSL, LVCMOS, LVDS, and LVPECL
- 4:4 input-to-output ratio with a maximum frequency of 350 MHz
- Supply range of 1.71 V to 3.47 V and operating temperature range of -40°C to 85°C
- Surface-mount 44-QFN (7x7) package with exposed pad
Applications
- Clock selection and distribution in communications infrastructure equipment
- Timing synchronization on server, storage, and backplane boards
- Reference clock routing for test and measurement equipment
- Mixed-logic clock delivery in embedded processing boards
Design & Procurement Notes
Designers should confirm that available clock sources and downstream loads match the supported input and output logic families, including LVCMOS, LVDS, LVPECL, and crystal inputs, and CML, HCSL, LVCMOS, LVDS, and LVPECL outputs. The 4:4 input-to-output ratio and single circuit should be considered when planning the clock tree, source selection, output loading, and differential pair requirements. Board layout should address the 44-QFN (7x7) exposed pad, surface-mount land pattern, and thermal dissipation under the -40°C to 85°C operating range. The 1.71 V to 3.47 V supply range should be checked against local power rails and voltage margining.
