Product details
Overview
LTC6930HMS8-4.19#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator delivering 4.194304MHz output with ±0.1% frequency accuracy over –40°C to 125°C, 105µA typical supply current at 32kHz/3V, <110µs start-up time, and RMS period jitter <0.15% at 3V - used as a precision clock source in industrial microcontroller systems requiring extended temperature operation.
For engineers reviewing the LTC6930HMS8-4.19#TRPBF datasheet, LTC6930HMS8-4.19#TRPBF pinout, LTC6930HMS8-4.19#TRPBF application, or LTC6930HMS8-4.19#TRPBF equivalent, key selection criteria include factory-programmed master frequency, 3-pin binary divider control (DIVA/DIVB/DIVC), MS8 package compatibility, long-term drift of 30ppm/√kHr, and operation from 1.7V–5.5V single supply.
Technical Context
The LTC6930HMS8-4.19#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its factory-set 4.194304MHz master oscillator across voltage and temperature extremes. Its internal binary divider (N = 1 to 128) selects final output frequency via three CMOS logic inputs (DIVA, DIVB, DIVC), enabling eight discrete frequencies from 32.768kHz to 4.194304MHz without external components.
It features dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate oscillator core from output driver noise, resulting in low deterministic jitter (<0.15% RMS at 3V) and glitch-free DIV pin switching within one output cycle. The 40Ω CMOS output driver supports up to 50pF capacitive or 1kΩ resistive load with 3ns rise/fall time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 4.194304MHz - fixed master oscillator frequency; output derived by integer division (÷1 to ÷128). |
| Frequency Accuracy | ±0.1% over full operating range (–40°C to 125°C, 1.7V–5.5V) - ensures timing compliance in harsh industrial environments. |
| Supply Current | 105µA typical at 32.768kHz/3V - enables multi-year battery life in low-duty-cycle sensor nodes. |
| Start-Up Time | <110µs - allows rapid wake-from-sleep in power-gated MCU applications without clock stabilization delay. |
| RMS Period Jitter | <0.15% at V+ = 3V - translates to ~180ps RMS at 4.194MHz, suitable for ADC sampling clocks and serial interface timing. |
| Operating Temp Range | –40°C to 125°C - qualified for under-hood automotive, industrial motor drives, and high-reliability embedded control. |
| Long-Term Drift | 30ppm/√kHr - predicts ~0.0198% cumulative error after 5 years of continuous operation. |
Pinout & Package
Package: 8-Lead Plastic MSOP (MS8), 3.00mm × 3.00mm footprint, 0.65mm pitch, exposed thermal pad not present (MSOP variant). Pin 1 marked by notch; pin 1 corner located at top-left when marking side faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive Supply Input | Dual supply pins reduce PSRR coupling; each requires local 0.1µF ceramic bypass to adjacent GND. |
| GND (Pins 2, 6) | Ground Reference | Dual ground pins provide low-inductance return paths for core oscillator and output driver separately. |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Binary Divider Control Inputs | CMOS logic inputs (VIH ≥ 1.25V, VIL ≤ 1.25V); set N = 1–128 via [DIVC][DIVB][DIVA] code per Table 1. |
| OUT (Pin 7) | CMOS Clock Output | 40Ω series resistance, 3ns rise/fall time; drives 5pF (2× HC loads) or up to 50pF with appropriate decoupling. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the nominal output frequency of the LTC6930HMS8-4.19#TRPBF?
The LTC6930HMS8-4.19#TRPBF is factory-programmed with a nominal master oscillator frequency of 4.194304MHz. This value is divided internally by powers of two (N = 1 to 128) based on DIVA/DIVB/DIVC pin states, yielding eight selectable output frequencies - including 4.194304MHz (÷1), 2.097152MHz (÷2), and down to 32.768kHz (÷128). The "4.19" suffix explicitly denotes this base frequency.
Does the LTC6930HMS8-4.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HMS8-4.19#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or crystal resonators. Only 0.1µF ceramic bypass capacitors between each V+ pin (1 and 8) and its adjacent GND pin (2 and 6) are needed for stable operation. This eliminates crystal matching tolerances, PCB layout sensitivity, and aging-related frequency drift inherent in quartz solutions.
What is the maximum operating temperature rating for the LTC6930HMS8-4.19#TRPBF?
The LTC6930HMS8-4.19#TRPBF is rated for operation from –40°C to 125°C, indicated by the "H" grade suffix. This specification is guaranteed across the full voltage range (1.7V–5.5V) and all eight divider settings. It is validated per the LTC6930H temperature grade definition and exceeds commercial (C) and industrial (I) variants, making it suitable for under-hood automotive, industrial motor drives, and high-ambient embedded systems.
How does the LTC6930HMS8-4.19#TRPBF achieve ±0.1% frequency accuracy over temperature and voltage?
The LTC6930HMS8-4.19#TRPBF achieves ±0.1% frequency accuracy using a proprietary switched-capacitor feedback loop that actively stabilizes its factory-trimmed master oscillator against temperature and supply variations. Internal regulation maintains constant bias conditions, while the dual-V+/dual-GND architecture minimizes noise coupling. This architecture - not quartz resonance - delivers consistent accuracy without external compensation circuitry or calibration.
Can the DIV pins of the LTC6930HMS8-4.19#TRPBF be changed dynamically during operation?
Yes, the DIVA, DIVB, and DIVC pins of the LTC6930HMS8-4.19#TRPBF can be reconfigured dynamically during normal operation. The device guarantees glitch-free, runt-pulse-free transitions within one output clock cycle after the divider control signals settle. This enables real-time clock scaling in applications such as adaptive power management or multi-rate peripheral interfacing without requiring reset or reinitialization.
