Product details

80 MHz fixed-frequency silicon oscillator in a 5-pin TSOT-23

The LTC6905IS5-80#TRPBF is a silicon oscillator from Analog Devices that delivers a fixed 80 MHz clock output without requiring a crystal, external resonator, or timing capacitor.

Supply voltage and current — sizing the power rail

The 7 mA supply current at 80 MHz is the nominal value; at the 5.5 V upper end the current will be slightly higher, but the part stays within the TSOT-23 thermal limits as long as the ambient stays below 85°C.

It is ROHS3 compliant, which satisfies EU and global environmental requirements for new designs. For volume BOM commitments, we source and quote per RFQ against the required quantity.

Package and footprint — TSOT-23-5 layout notes

The TSOT-23-5 package has a 0.95 mm pitch and a body size of 2.9 mm × 1.6 mm. The recommended land pattern is in the datasheet; the small footprint allows placement near the load to minimise clock trace length.

Frequently asked questions

Can LTC6905IS5-80#TRPBF directly replace a crystal oscillator?

Yes, it is a silicon oscillator that outputs a rail-to-rail square wave at 80 MHz, so it can replace a crystal + oscillator circuit in many digital clock applications. No external load capacitors or feedback resistor are needed. Confirm that the output drive strength and jitter meet your receiver's input requirements.

What is the closest functional second-source for LTC6905IS5-80#TRPBF?

The LTC6905IS5-80#TRMPBF is the same die in a different reel packaging variant (Cut Tape / Digi-Reel). For a different frequency, the LTC6905IS5-96#TRMPBF (96 MHz) and LTC6905IS5-100#TRPBF (100 MHz) are pin-compatible siblings in the same LTC6905 family.
