Product details
Overview
LTC6930IDCB-8.19#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator delivering factory-programmed 8.192MHz master frequency with user-selectable divide-by-1 to -128 outputs (64.0kHz to 8.192MHz), ±0.1% frequency accuracy over –40°C to 85°C, <110µs start-up time, and 1.7V–5.5V single-supply operation. It serves as a precision timing source in battery-powered microcontroller clocking and portable instrumentation.
For engineers reviewing the LTC6930IDCB-8.19#TRPBF datasheet, LTC6930IDCB-8.19#TRPBF pinout, LTC6930IDCB-8.19#TRPBF application, or LTC6930IDCB-8.19#TRPBF equivalent, key selection criteria include guaranteed ±0.1% accuracy across temperature, ultralow 190µA typical supply current at 32kHz/3V, DFN-8 package footprint compatibility, and deterministic DIV-pin switching without output glitches.
Technical Context
The LTC6930IDCB-8.19#TRPBF integrates a proprietary switched-capacitor-controlled master oscillator (factory-set to 8.192MHz) and a binary divider chain (÷1 to ÷128) controlled by three CMOS logic inputs (DIVA/DIVB/DIVC). Its internal regulation minimizes supply-induced frequency drift (0.07%/V).
Operation requires no external timing components-only 0.1µF bypass capacitors on dual V+ pins (Pins 1 & 8). The output driver features 40Ω series resistance, 3ns rise/fall time, and glitch-free transitions during DIV pin changes, enabling clean clock distribution 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-32.768E | 32.768kHz-only MEMS oscillator; ±10ppm (±0.001%) accuracy; 1.62–3.63V supply | Fixed-frequency only; no programmable division; superior accuracy but no frequency flexibility | Select when absolute lowest jitter (<1ppm) and highest stability at 32.768kHz are required, and frequency agility is unnecessary. |
| MAX7375ETE+ | 32.768kHz–2MHz programmable oscillator; ±500ppm (±0.05%) accuracy; 1.7–5.5V supply | Wider frequency range but lower accuracy; higher 1.2mA typical supply current at 1MHz | Select when cost sensitivity outweighs accuracy needs and 0.05% tolerance is acceptable for non-critical timing. |

FAQ
What is the maximum output frequency supported by the LTC6930IDCB-8.19#TRPBF?
The LTC6930IDCB-8.19#TRPBF supports a maximum output frequency of 8.192MHz, achieved when the DIVA/DIVB/DIVC pins are set to [000] (÷1 division of the factory-programmed 8.192MHz master oscillator). This is confirmed in Table 1 of the datasheet and applies across the full –40°C to 85°C operating range with ±0.1% accuracy.
Does the LTC6930IDCB-8.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930IDCB-8.19#TRPBF does not require external load capacitors. It is a fully integrated silicon oscillator with an on-chip master oscillator and divider. Only 0.1µF ceramic bypass capacitors on each V+ pin (Pins 1 and 8) to adjacent GND pins are required-no crystal, trim caps, or matching networks are needed.
How does the LTC6930IDCB-8.19#TRPBF achieve ±0.1% frequency accuracy over temperature?
The LTC6930IDCB-8.19#TRPBF achieves ±0.1% frequency accuracy over –40°C to 85°C through a proprietary switched-capacitor feedback loop that actively regulates the master oscillator's frequency against temperature variation. This architecture, combined with factory trimming, eliminates the need for external compensation circuits while maintaining tight tolerance across the industrial temperature range.
Can the DIV pins of the LTC6930IDCB-8.19#TRPBF be changed dynamically during operation?
Yes, the DIVA/DIVB/DIVC pins of the LTC6930IDCB-8.19#TRPBF can be changed dynamically during operation. The device guarantees glitch-free output transitions within one clock cycle of the DIV pin change, with no runt pulses or metastability-enabling real-time frequency reconfiguration in adaptive systems.
What is the recommended PCB layout for thermal management of the LTC6930IDCB-8.19#TRPBF?
The LTC6930IDCB-8.19#TRPBF DFN package includes an exposed thermal pad (Pin 9) that must be soldered to a solid copper ground plane. Recommended layout uses thermal vias under the pad connected to an internal or bottom-layer ground plane. Dual V+ and GND pins (Pins 1/8 and 2/6) should each have local 0.1µF bypass capacitors placed as close as possible to minimize supply impedance and EMI.
