Product details
Overview
LTC6930HMS8-8.19#PBF from Analog Devices (formerly Linear Technology) is a digitally controlled, precision silicon oscillator delivering factory-programmed 8.192MHz master frequency with user-selectable divide-by-1 to 128 outputs (64kHz to 8.192MHz). It features ±0.1% frequency accuracy over –40°C to 125°C, <110µs start-up time, and 1.7V–5.5V single-supply operation. It serves as a low-power timing source in industrial microcontroller clocking and battery-powered instrumentation.
For engineers reviewing the LTC6930HMS8-8.19#PBF datasheet, LTC6930HMS8-8.19#PBF pinout, LTC6930HMS8-8.19#PBF application, or LTC6930HMS8-8.19#PBF equivalent, this page provides verified specifications, MS8 package terminal mapping, temperature-grade performance data, and validated alternatives for high-reliability embedded timing design.
Technical Context
The LTC6930HMS8-8.19#PBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 8.192MHz master oscillator across voltage and temperature extremes. Its digital control architecture uses three CMOS input pins (DIVA/DIVB/DIVC) to select binary division ratios (1–128), enabling eight discrete output frequencies without external components.
It integrates dual V+ supply pins and isolated GND paths to minimize coupling between the oscillator core and output driver, achieving typical RMS period jitter <0.15% at 3V and deterministic glitch-free transitions when DIV pins are reconfigured - critical for real-time system synchronization.
Key Specifications

| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Binary divider control inputs | CMOS logic inputs (VIL ≤ 1.25V, VIH ≥ 1.4V); set N = 2(4×DIVC + 2×DIVB + DIVA) for ÷N output |
| OUT (Pin 7) | CMOS clock output | 40Ω series resistance, 3ns rise/fall time; drives up to 50pF load; held low during power-up to prevent glitches |
Key Features
| Feature | Design Value |
|---|---|
| No external timing components required | Reduces BOM count and PCB area; eliminates crystal load capacitor tuning and aging drift concerns |
| Ultralow power consumption scaling | Supply current varies linearly with output frequency - enables precise power budgeting across sleep/wake states |
| Glitch-free DIV pin reconfiguration | Output transitions cleanly within one clock cycle - avoids race conditions in dynamic clock domain switching |
| Factory-trimmed master oscillator | 8.192MHz master frequency trimmed to ±0.09% at 25°C - ensures consistent base accuracy across production lots |

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 MEMS oscillator only; no programmable division; ±10ppm initial accuracy | Fixed-frequency RTC use only; lacks multi-frequency flexibility of LTC6930HMS8-8.19#PBF | Select when absolute lowest power (<1µA) and fixed 32kHz are sufficient, and temperature range is limited to –40°C to +85°C. |
| MAX7375EKA+T | 32.768kHz to 2MHz programmable oscillator; ±500ppm accuracy over –40°C to +85°C; no H-grade option | Lower accuracy and narrower temperature range than LTC6930H; lacks 8.192MHz master capability | Select for cost-sensitive consumer designs where ±0.05% accuracy is unnecessary and extended temperature operation is not required. |

FAQ
What is the maximum output frequency achievable with LTC6930HMS8-8.19#PBF?
The LTC6930HMS8-8.19#PBF has a factory-programmed master oscillator frequency of 8.192MHz. When configured with DIVA=DIVB=DIVC=0 (÷1 mode), it delivers exactly 8.192MHz at the OUT pin. This is the highest frequency available from this specific part number; higher frequencies require a different LTC6930 variant (e.g., LTC6930HMS8-8.00#PBF for 8.000MHz base).
Does LTC6930HMS8-8.19#PBF support operation below 1.7V?
No. The absolute minimum supply voltage for LTC6930HMS8-8.19#PBF is 1.7V, as specified in the Absolute Maximum Ratings table. Operation below this voltage is not characterized and may result in undefined behavior, including failure to start or inaccurate frequency output. The device is optimized for single-cell Li-ion (2.7–4.2V) or dual-AA (2.4–3.2V) operation.
How does the LTC6930HMS8-8.19#PBF achieve ±0.1% accuracy over –40°C to +125°C?
The LTC6930HMS8-8.19#PBF achieves ±0.1% accuracy across its full operating temperature range through a proprietary switched-capacitor feedback loop that actively compensates for temperature-induced frequency drift in the silicon resonator. This on-chip trimming and regulation - combined with H-grade process qualification - eliminates the need for external compensation networks used in lower-accuracy oscillators.
Can the DIV pins of LTC6930HMS8-8.19#PBF be changed dynamically during operation?
Yes. The DIVA, DIVB, and DIVC pins of LTC6930HMS8-8.19#PBF support live reconfiguration. The output transitions cleanly to the new divided frequency within one clock cycle of the final DIV pin change, with no glitches, runt pulses, or metastability - enabling dynamic clock scaling in power-managed systems.
What is the recommended PCB layout practice for minimizing jitter on LTC6930HMS8-8.19#PBF?
To minimize jitter on LTC6930HMS8-8.19#PBF, place separate 0.1µF ceramic bypass capacitors directly between each V+ pin (1 and 8) and its adjacent GND pin (2 and 6), using shortest possible traces. Route the OUT signal away from noisy supply lines and isolate it from V+/GND pins. Avoid routing beneath the device body, and ensure solid ground plane coverage under the MSOP footprint to suppress ground bounce.
