VSC8115XYA-05-T

Overview

The VSC8115XYA-05-T is a clock recovery integrated circuit manufactured by Microchip Technology. It supports a Clock Recovery Unit (CRU) frequency of 622 MHz, suitable for synchronous Ethernet applications. The device provides LVDS and LVPECL output types to interface with downstream logic. It operates on a single 3.3 V power supply with a maximum voltage rating of 3.3 V. The component is housed in a TSSOP-20 surface-mount package and functions within an operating temperature range of 0°C to +85°C. Power dissipation is specified at 155 mW.

Procurement Notes

Verify the specific suffix -05-T against official Microchip documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status via the manufacturer's current datasheet before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this component when a dedicated 622 MHz clock recovery solution with LVDS/LVPECL outputs is required. Verify that the 0°C to +85°C industrial temperature range meets environmental constraints. Compare power dissipation limits against available thermal management capabilities in the target PCB layout.

Part Context

This part belongs to the VSC8115 family of clock and data recovery ICs from Microchip Technology. It is categorized under timers and support products, specifically designed for clock generation and recovery tasks in networking equipment. The TSSOP-20 package offers a compact footprint for high-density board designs.

Replacement Considerations

Consult Microchip official substitution guides for verified alternatives. Generic clock recovery ICs may not match the specific 622 MHz CRU performance or LVDS/LVPECL output drive requirements.
