Product details
Overview
LTC6930HMS8-8.19#TRPBF from Analog Devices (acquired Linear Technology) is a digitally controlled silicon oscillator delivering factory-programmed 8.192MHz master frequency with user-selectable divide-by-1 to 128 outputs (64kHz–8.192MHz), ±0.1% frequency accuracy over –40°C to 125°C, 105µA typical supply current at 32kHz/3V, and <110µs power-on delay. It serves as a precision timing source in industrial sensor nodes requiring stable low-power clocking under wide temperature and supply voltage variation.
For engineers reviewing the LTC6930HMS8-8.19#TRPBF datasheet, LTC6930HMS8-8.19#TRPBF pinout, LTC6930HMS8-8.19#TRPBF application, or LTC6930HMS8-8.19#TRPBF equivalent, key selection criteria include guaranteed ±0.1% initial accuracy at 125°C, MSOP-8 package compatibility with high-density layouts, digital frequency selection via three CMOS input pins, and operation from 1.7V–5.5V single supply without external components.
Technical Context
The LTC6930HMS8-8.19#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 8.192MHz master oscillator across temperature and supply voltage. Its control architecture separates power delivery paths for oscillator core and output driver to minimize deterministic jitter.
Digital inputs DIVA/DIVB/DIVC configure binary-coded dividers (1–128) that scale the master frequency, enabling eight discrete output frequencies from 64kHz to 8.192MHz. The output stage features a 40Ω CMOS driver with 3ns rise/fall time and glitch-free transitions during divider changes.
Key Specifications

FAQ
What is the maximum output frequency achievable with the LTC6930HMS8-8.19#TRPBF?
The LTC6930HMS8-8.19#TRPBF delivers a factory-programmed 8.192MHz master oscillator frequency. When configured with DIVA=DIVB=DIVC=0 (divide-by-1), the device outputs exactly 8.192MHz. This is the maximum frequency available from the LTC6930HMS8-8.19#TRPBF, as higher frequencies are not supported by its internal architecture or characterization.
Does the LTC6930HMS8-8.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HMS8-8.19#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or crystal resonators. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are needed for stable operation, as specified in the recommended layout.
Can the LTC6930HMS8-8.19#TRPBF operate from a single 1.8V supply?
Yes, the LTC6930HMS8-8.19#TRPBF supports supply voltages from 1.7V to 5.5V. At 1.8V, it maintains full functionality including all eight divider ratios, ±0.1% frequency accuracy over –40°C to 125°C, and <110µs start-up time, making it compatible with modern low-voltage microcontrollers and battery chemistries.
How does the LTC6930HMS8-8.19#TRPBF handle transitions between different DIV settings?
The LTC6930HMS8-8.19#TRPBF transitions between DIV settings glitch-free within one output clock cycle. The output remains stable during reconfiguration-no runt pulses, slivers, or frequency discontinuities occur-enabling reliable dynamic clock scaling in power-aware embedded systems without software workarounds.
What is the long-term frequency stability specification for the LTC6930HMS8-8.19#TRPBF?
The LTC6930HMS8-8.19#TRPBF exhibits typical long-term frequency drift of 30ppm/√kHr. Over five years of continuous operation (43.83kHr), this translates to approximately 0.0198% total drift. Drift during unpowered storage is estimated at ~1/10th of powered drift, or 3ppm/√kHr, based on silicon ion migration physics.
