Product details

Programmable silicon oscillator, 1 kHz to 33 MHz

The LTC1799CS5#TRMPBF is a silicon oscillator that generates a square-wave output from 1 kHz to 33 MHz, set by a single external resistor. No crystal, ceramic resonator, or external timing capacitor is needed — the frequency is programmed by the resistor value between the SET pin and ground. Supply current is 700 µA typical across the full frequency range, making it a low-power alternative to crystal oscillators in battery-operated or power-sensitive designs. The 2.7V to 5.5V supply range lets it run directly from a 3.3V or 5V rail without a separate LDO.

Active production — no end-of-life concern

The part is ROHS3 compliant and available in Tape & Reel (TR) or Cut Tape (CT) packaging.

TSOT-23-5 footprint — layout checklist

Package is the 5-lead Thin SOT-23 (TSOT-23-5), supplier device package TSOT-23-5. No exposed pad — thermal relief is through the leads only. A bypass capacitor at the V+ pin within 5 mm of the package is sufficient for decoupling.

Frequently asked questions

What is the closest functional second-source for LTC1799CS5#TRMPBF?

The LTC1799CS5#TRPBF is functionally identical — same frequency range, supply voltage, and temperature grade — but supplied in Tape & Reel only (no Cut Tape option).

How do I set the output frequency on the LTC1799?

The output frequency is set by a single resistor (RSET) connected between the SET pin and ground. The relationship is fO = 10 MHz × (10 kΩ / RSET). For example, a 10 kΩ resistor gives 10 MHz; a 100 kΩ resistor gives 1 MHz. The resistor value should be between 3.3 kΩ and 1 MΩ to stay within the 1 kHz to 33 MHz range.
