Product details
Overview
LTC6930CDCB-5.00#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled, precision silicon oscillator with factory-set 5.000000MHz master frequency, selectable via DIV pins across eight output frequencies from 39.0625kHz to 5.000MHz. It delivers <±0.1% frequency accuracy over 0°C to 70°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time - ideal for low-power microcontroller clocking in portable instrumentation.
For engineers reviewing the LTC6930CDCB-5.00#TRPBF datasheet, LTC6930CDCB-5.00#TRPBF pinout, LTC6930CDCB-5.00#TRPBF application, or LTC6930CDCB-5.00#TRPBF equivalent, key selection criteria include its ±0.1% initial accuracy at 25°C, 1.7V–5.5V single-supply operation, 8-pin DFN (2mm × 3mm) package with exposed pad, RMS period jitter <0.15% at 3V, and digital frequency division control via three CMOS input pins.
Technical Context
The LTC6930CDCB-5.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator against temperature and supply variation. Its digital divider architecture uses three binary inputs (DIVA/DIVB/DIVC) to select one of eight fixed division ratios (1–128), yielding precise output frequencies without external components.
It features dual V+ and GND pins adjacent to the OUT pin to minimize coupling between the control loop and output driver, enabling clean waveform generation even under 50pF capacitive loading. Internal supply regulation ensures <0.07%/V frequency drift, while fast 2ns rise/fall times and 40Ω output resistance support robust signal integrity in noise-sensitive embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1533AI-H4-33E-32.768D | 32.768kHz fixed-frequency MEMS oscillator; ±20ppm accuracy; no digital division | Only suitable for RTC backup; lacks programmable frequency and wide-range operation | Select only if fixed 32.768kHz is sufficient and MEMS reliability is prioritized over flexibility |

FAQ
What is the nominal master oscillator frequency of the LTC6930CDCB-5.00#TRPBF?
The LTC6930CDCB-5.00#TRPBF has a factory-programmed master oscillator frequency of exactly 5.000000MHz. This value is fixed and cannot be altered; output frequencies are generated by dividing this master frequency using the DIVA, DIVB, and DIVC pins to select integer division ratios from 1 to 128, yielding eight discrete output frequencies ranging from 39.0625kHz to 5.000MHz.
Does the LTC6930CDCB-5.00#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930CDCB-5.00#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or resonators. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are needed for stable operation. This eliminates crystal matching tolerances, PCB layout sensitivity, and aging-related frequency drift inherent in quartz-based solutions.
What is the maximum capacitive load the LTC6930CDCB-5.00#TRPBF can drive reliably?
The LTC6930CDCB-5.00#TRPBF is specified to drive up to 50pF capacitive load while maintaining performance within datasheet limits. Its 40Ω output resistance and controlled 2ns rise/fall times ensure signal integrity under this load. Driving loads beyond 50pF may increase supply current nonlinearly and degrade jitter; for heavier loads, a buffer amplifier is recommended to preserve timing accuracy.
How does the LTC6930CDCB-5.00#TRPBF achieve ±0.1% frequency accuracy over temperature?
The LTC6930CDCB-5.00#TRPBF achieves ±0.1% frequency accuracy from 0°C to 70°C through a proprietary switched-capacitor feedback loop that actively stabilizes its internal 5.000000MHz master oscillator. Combined with internal supply regulation (0.07%/V drift) and DCB package thermal characteristics (0.001%/°C), this architecture maintains tight tolerance without external compensation components or calibration.
Can the DIV pins of the LTC6930CDCB-5.00#TRPBF be changed dynamically during operation?
Yes, the DIVA, DIVB, and DIVC pins of the LTC6930CDCB-5.00#TRPBF can be reconfigured dynamically during operation. The device responds to new DIV settings within one output clock cycle, with no glitches, runt pulses, or undefined states on the OUT pin. This enables real-time clock frequency scaling in response to system load or power mode changes without requiring reset or reinitialization.
