Frequently Asked Questions
What is the programmable frequency range of the LTC6903HMS8#PBF and how is it configured?
The LTC6903HMS8#PBF covers an output frequency range of 1 kHz to 68 MHz, fully programmable via a 3-wire SPI interface. No external crystal or resonator is required since the device uses an internal RC oscillator with digital tuning. This makes it easy to change clock frequencies on the fly in embedded and test systems without board redesign.
How does the LTC6903HMS8#PBF output enable function benefit low-power or multi-clock board designs?
The built-in output enable (OE) pin allows the host controller to gate the clock output when it is not needed, reducing dynamic power consumption and EMI in battery-powered designs. In multi-clock PCB architectures, OE can be used to multiplex clock domains and select which subsystem is active at a given time. This feature is particularly useful in portable instruments, IoT nodes, and FPGA dev boards operating from a 3.3 V or 5 V rail.
For a compact frequency synthesizer design, how much board area does the LTC6903HMS8#PBF MSOP-8 package occupy?
The MSOP-8 package used by the LTC6903HMS8#PBF measures approximately 3.0 mm x 3.0 mm with 0.65 mm pin pitch, providing a very small footprint for a complete 1 kHz to 68 MHz programmable oscillator solution. Compared to crystal oscillators or DDS modules, this single-package solution eliminates the need for a separate crystal, resonator, or tuning capacitors, saving significant PCB area in space-constrained designs.
When is the LTC6903HMS8#PBF preferred over a fixed-frequency crystal oscillator in system clock design?
The LTC6903HMS8#PBF is preferred when the system clock frequency needs to be changed programmatically during operation or across different product variants using the same PCB. Fixed crystal oscillators are locked to a single frequency and require physical replacement for frequency changes, while the LTC6903 can be reprogrammed via SPI in microseconds. This advantage is critical in multi-protocol communications hardware, adaptive test equipment, and platforms requiring 68 MHz or lower programmable reference clocks.
