- CMOS output with 3 ns maximum fall time drives logic circuits directly at 5 pF load without buffer stages
- Crystal-free silicon oscillator design removes the need for an external crystal, reducing BOM cost and PCB area
Applications
The LTC6930IMS8-8.19#PBF is a crystal-free silicon oscillator ideal for generating standard binary clock frequencies in embedded microcontroller systems, ADC timing, and communication baud rate generation. Its built-in frequency divider chain provides clocks at 8.192, 4.096, 2.048, 1.024, 0.512, 0.256, 0.128, and 0.064 MHz, making it suitable for real-time clocks, telecom timing, and medical device timing circuits. The MSOP-8 package and surface-mount design simplify integration into space-constrained industrial control and IoT devices.

Frequently Asked Questions
What output frequencies does LTC6930IMS8-8.19#PBF provide and how does the divider chain simplify multi-frequency system design?
The LTC6930IMS8-8.19 generates 8 binary-divided frequencies: 8.192 MHz, 4.096 MHz, 2.048 MHz, 1.024 MHz, 512 kHz, 256 kHz, 128 kHz, and 64 kHz from a single device. This eliminates 7 external divider stages that would otherwise require separate 74HC-series counters or FPGA logic, saving approximately 50 to 100 mW of power and multiple PCB footprints.
Why is the 8.192 MHz frequency of LTC6930IMS8-8.19#PBF particularly useful for real-time clock and ADC sampling applications?
The 8.192 MHz base frequency is a power-of-2 multiple of common RTC tick rates: dividing by 8192 yields exactly 1 kHz, and further division gives 1 Hz for second-accurate timekeeping. For audio ADCs requiring sample rates of 8 kHz or 16 kHz, the 8.192 MHz source divides cleanly without fractional dividers, minimizing jitter below 1 ns in precision sampling chains.
How does the crystal-free design of LTC6930IMS8-8.19#PBF reduce system cost and improve reliability compared to quartz-crystal oscillators?
By integrating the frequency reference on silicon, the LTC6930IMS8-8.19 eliminates an external quartz crystal and its 2 load capacitors, saving approximately 3 components and 10 to 15 mm² of PCB area per clock channel. Silicon oscillators also have higher shock and vibration tolerance than quartz crystals, improving MTBF in industrial and automotive environments where mechanical stress degrades quartz resonators over time.
What output load capacitance does LTC6930IMS8-8.19#PBF support and how does this affect signal integrity?
The LTC6930IMS8-8.19 is specified for a 5 pF output load with a maximum fall time of 3 ns. For higher capacitive loads such as 15 to 50 pF from long PCB traces, a 33 to 50 ohm series resistor between the oscillator output and the destination reduces overshoot and ringing while keeping propagation delay below 5 ns, maintaining valid CMOS logic levels at the receiver.
