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. The part is housed in a 5-lead TSOT-23-5 package (SOT-23-5 Thin), which occupies minimal board area and is compatible with standard surface-mount assembly processes.
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.
Lifecycle and compliance — active production, ROHS3
It is ROHS3 compliant, which satisfies EU and global environmental requirements for new designs. The part is supplied in Tape & Reel (TR) packaging, with Cut Tape (CT) also available for prototyping. 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.
