Applications
The LTC6903HMS8#TRPBF is used in embedded systems, instrumentation, and communications equipment where a software-configurable clock source from 1 kHz to 68 MHz is needed without crystal oscillator constraints. Its SPI interface allows the host microcontroller to dynamically change the output frequency, making it ideal for frequency-hopping protocols, adjustable sample-rate ADC/DAC clocking, and mixed-signal testing. The output enable pin further supports low-power clock gating in battery-operated designs.

Frequently Asked Questions
What is the programmable frequency range of the LTC6903HMS8#TRPBF and how is it configured?
The LTC6903HMS8#TRPBF is programmable from 1 kHz to 68 MHz via a 3-wire SPI interface using a simple register write from any microcontroller. No external crystal, resistor, or capacitor is required to set the frequency, significantly reducing BOM cost and PCB area compared to crystal oscillator solutions while enabling run-time frequency changes.
How does the output enable function on the LTC6903HMS8#TRPBF help in low-power embedded designs?
The output enable pin on the LTC6903HMS8#TRPBF allows the host processor to gate the clock output high or low, stopping unnecessary clock transitions to downstream logic and reducing dynamic power consumption by tens of milliwatts in idle operating modes. This feature is especially useful in battery-powered IoT devices with duty-cycled operation at supply voltages of 2.7 V to 5.5 V.
When would an engineer choose the LTC6903HMS8#TRPBF over a fixed-frequency crystal oscillator for an ADC clocking application?
An engineer would select the LTC6903HMS8#TRPBF when the ADC sample rate must be changed in firmware at run time, such as switching between 1 kHz audio sampling and 10 MHz RF signal capture within the same hardware platform. The SPI-programmable 1 kHz to 68 MHz range covers the full span of common ADC clock requirements in a single 8-pin MSOP device, eliminating the need for multiple fixed oscillators.
