Product details

MEMS oscillator with LVDS output at 166 MHz

The DSC1103CI2-166.0000: LVDS signalling provides low-jitter, differential clock distribution for high-speed interfaces such as Ethernet PHYs, FPGAs, and SerDes transceivers — the 100-ohm termination is built into the receiver, so no external bias network is needed.

Active current draw is 32 mA max at 166 MHz — the MEMS resonator core keeps the power lower than a comparable quartz-based oscillator at this frequency.

The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that matches standard 3.2 x 2.5 mm oscillator land patterns, simplifying PCB layout reuse.

Frequently asked questions

What is the pinout of DSC1103CI2-166.0000?

Design engineers need to validate the footprint and signal connections before PCB layout.

Where can I buy DSC1103CI2-166.0000 in small quantities?

Sourcing buyers and hobbyists need to know which distributors stock the part for prototyping or low-volume orders.

Is DSC1103CI2-166.0000 obsolete or end-of-life?

Maintenance techs and brokers need lifecycle status to avoid designing in a part that may become unavailable.

What is the typical price for DSC1103CI2-166.0000?

Procurement buyers need price benchmarks for budgeting and negotiating with suppliers.

What are the direct alternatives to DSC1103CI2-166.0000?

Engineers evaluating second sourcing or facing supply constraints need cross-reference parts with same footprint and specs.

Does DSC1103CI2-166.0000 work with 2.5V supply?

Designers need to confirm compatibility with their specific voltage rail to ensure proper LVDS startup and operation.
