SI52142-A01AGMR

Product Overview

The SI52142-A01AGMR from Skyworks Solutions Inc. is an active application-specific clock/timing integrated circuit intended for PCI Express (PCIe) use. It is a single-circuit device with a maximum output frequency of 200 MHz, a 1:3 input-to-output ratio, and HCSL differential output. The input can be a clock or crystal source, while the differential input/output configuration is No/Yes. The device operates from a 3.135 V to 3.465 V supply and is specified for an operating temperature range of -40°C to 85°C. It is supplied in a surface-mount 24-WFQFN exposed-pad package, with a supplier device package of 24-QFN (4x4).

Key Features

• PCI Express (PCIe) main purpose with integrated PLL and a maximum frequency of 200 MHz.
• Single circuit output, HCSL differential output, and 1:3 input-to-output ratio.
• Accepts clock or crystal input with differential input/output No/Yes.
• Supply voltage range of 3.135 V to 3.465 V and operating temperature range of -40°C to 85°C.
• Surface-mount 24-WFQFN exposed-pad package, supplier device package 24-QFN (4x4), lifecycle status Active.

Applications

• PCIe reference clock generation in a board that uses a 200 MHz HCSL timing output.
• Clock generation from a crystal or clock input for PCIe-oriented timing paths.
• Single-output differential clock delivery where the circuit requires a No/Yes input/output differential configuration and 1:3 ratio.

Design & Procurement Notes

Verify that the PCIe-oriented clock function, 200 MHz maximum output, HCSL differential output, 1:3 input-to-output ratio, and clock or crystal input fit the timing architecture. Confirm the 3.135 V to 3.465 V supply and -40°C to 85°C operating range against the board environment. The 24-WFQFN exposed-pad package and 24-QFN (4x4) supplier package should be matched to the PCB layout and assembly process. The Active status can be used as a current lifecycle indication.
