Frequently Asked Questions
Over what frequency range can the LTC6904IMS8#PBF be programmed, and how is the frequency set?
The LTC6904IMS8#PBF is programmable across a continuous range from 0.001 MHz to 68 MHz using an I2C-compatible 2-wire serial interface. A 10-bit register word sets the output frequency without any external crystal, inductor, or capacitor, simplifying PCB layout and reducing BOM cost by at least 3 to 5 passive components compared to a traditional crystal oscillator circuit.
How does the output-enable pin on the LTC6904IMS8#PBF help in power-sensitive embedded designs?
The dedicated output-enable input allows a host microcontroller to gate the 68 MHz clock output completely, halting switching activity and reducing dynamic power consumption during sleep or low-activity modes. In a typical 3.3 V battery-operated system, disabling the clock output can cut oscillator-related supply current from several milliamps to under 10 µA, extending battery run time noticeably in IoT sensor nodes or handheld instruments.
What makes the LTC6904IMS8#PBF a better fit than a fixed-frequency crystal oscillator for automotive telematics applications?
Unlike a fixed-frequency crystal oscillator locked to a single frequency, the LTC6904IMS8#PBF can be reprogrammed over I2C to any frequency between 0.001 MHz and 68 MHz, making it suitable for multi-protocol automotive telematics platforms that must switch between CAN, LIN, and Ethernet clocking domains. Its automotive-grade qualification covering -40°C to 125°C operating temperature and 1 ns fall time ensure signal integrity across the full engine-compartment temperature range.
