DS3102GN

Overview

The DS3102GN is a timing line card integrated circuit manufactured by Microchip Technology, designed for ATM/SONET/SDH support applications. It operates within a supply voltage range of 1.62V to 1.98V and supports a maximum frequency of 312.5MHz. The device features an internal PLL and accepts CMOS, LVDS, LVPECL, or TTL inputs, providing corresponding outputs. Packaged in an 81-LBGA (CSBGA) case measuring 10x10mm, it functions reliably across an industrial temperature range of -40°C to 85°C.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements of 1.62V to 1.98V. Confirm that the 81-CSBGA footprint matches the PCB layout design before procurement.

Selection Notes

Select this component when designing SONET/SDH or Ethernet timing circuits requiring high-frequency stability up to 312.5MHz. The built-in PLL simplifies clock distribution designs. Ensure the application environment stays within the specified -40°C to 85°C operational range for reliable performance.

Part Context

This part belongs to the Microchip Technology timing and clock generator family. It serves as a specialized solution for telecom line cards, replacing discrete clocking components with a single integrated circuit that handles complex format conversions and frequency synthesis.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 81-CSBGA package dimensions and supports the required 1.62V-1.98V supply voltage range.
