Product details
Overview
LTC6930CMS8-4.19#TRPBF from Analog Devices (acquired Linear Technology) is a digitally controlled silicon oscillator delivering factory-programmed 4.194304MHz output with ±0.1% frequency accuracy over –40°C to 85°C, 105µA supply current at 32kHz/3V, <110µs start-up time, and RMS period jitter <0.15% - used as a precision clock source in battery-powered microcontroller systems.
For engineers reviewing the LTC6930CMS8-4.19#TRPBF datasheet, LTC6930CMS8-4.19#TRPBF pinout, LTC6930CMS8-4.19#TRPBF application, or LTC6930CMS8-4.19#TRPBF equivalent, key selection criteria include guaranteed initial accuracy, ultra-low power across 1.7–5.5V supply, fast wake-up timing, MSOP-8 package compatibility, and digital frequency division via DIVA/DIVB/DIVC pins without external components.
Technical Context
The LTC6930CMS8-4.19#TRPBF integrates a factory-trimmed master oscillator (4.194304MHz) with a programmable binary divider (÷1 to ÷128), enabling eight discrete output frequencies between 32.768kHz and 4.194304MHz. Its proprietary switched-capacitor control loop maintains stability across temperature and supply voltage variations.
It uses dual V+ pins (1,8) and dual GND pins (2,6) to isolate oscillator core from output driver noise, achieving <0.15% RMS period jitter at 3V and typical 3ns rise/fall time. The device operates fully functional from –40°C to 85°C (I-grade) with no external timing components required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 4.194304MHz - fixed master oscillator frequency; output selectable via internal divider (÷1 to ÷128). |
| Initial Accuracy | ±0.09% max at 25°C - ensures timing-critical firmware boot sequences meet spec without calibration. |
| Supply Range | 1.7V to 5.5V - supports direct operation from single Li-ion cell or two AA batteries. |
| Start-Up Time | <110µs - enables rapid wake-from-sleep in duty-cycled sensor nodes and portable devices. |
| Supply Current | 105µA typ at 32kHz/3V - extends battery life in low-frequency real-time clock applications. |
| RMS Period Jitter | <0.15% at 3V - meets jitter budget for UART, SPI, and I²C peripheral clocking at up to 4.194MHz. |
| Operating Temp | –40°C to +85°C - qualified for industrial ambient environments without derating. |
Pinout & Package
Package: 8-Lead Plastic MSOP (MS8), 3mm × 3mm footprint, 0.65mm pitch, exposed thermal pad not present (MSOP variant). Pin 1 marked by notch; top-side marking "LTCKZ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive Supply Input | Dual supply pins reduce supply impedance; each requires local 0.1µF ceramic bypass to adjacent GND. |
| GND (Pins 2, 6) | Ground Reference | Dual ground pins provide low-inductance return path; must be connected together on PCB. |
| OUT (Pin 7) | CMOS Clock Output | 40Ω series resistance, 3ns rise/fall time; drives ≤50pF load or 1kΩ resistive load cleanly. |
| DIVA (Pin 3) | Frequency Divider Control | Binary LSB input; logic high selects ÷2, ÷4, ÷8, etc., per Table 1; CMOS-compatible threshold ~1.25V. |
| DIVB (Pin 4) | Frequency Divider Control | Binary middle bit; state determines exact divide ratio (e.g., [DIVC][DIVB][DIVA] = 001 → ÷2). |
| DIVC (Pin 5) | Frequency Divider Control | Binary MSB input; three pins collectively select one of eight output frequencies from master 4.194304MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Digital frequency selection | Three CMOS inputs (DIVA/DIVB/DIVC) configure 8 discrete output frequencies without external components or trimming. |
| Ultralow power startup | 105µA typical supply current at 32kHz/3V enables multi-year operation on coin-cell batteries in RTC applications. |
| Supply-insensitive timing | 0.07%/V frequency drift ensures stable clocking across battery discharge curves from 3.6V to 2.0V. |
| Glitch-free DIV switching | Output transitions cleanly within one clock cycle when DIV pins change - no runt pulses or metastability. |
| Robust output drive | 40Ω CMOS output with controlled edge rates minimizes EMI while driving 5pF (two HC loads) or up to 50pF directly. |

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 initial accuracy; 1.62–3.63V supply; 3.2µA typical current. | Fixed-frequency only; no digital division; optimized for ultra-low-power RTC, not general-purpose MCU clocks. | Select when only 32.768kHz is needed and sub-µA sleep current is critical. |

FAQ
What is the nominal output frequency of the LTC6930CMS8-4.19#TRPBF?
The LTC6930CMS8-4.19#TRPBF is factory-programmed with a nominal master oscillator frequency of 4.194304MHz. Its output frequency is determined by internal binary division (÷1 to ÷128) selected via the DIVA, DIVB, and DIVC pins. At ÷1 setting, the output is exactly 4.194304MHz - commonly used for UART baud rate generation and MCU system clocks.
Does the LTC6930CMS8-4.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930CMS8-4.19#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or tuning components. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are needed for stable operation - eliminating crystal matching uncertainty and board area typically reserved for 12–22pF capacitors.
What is the guaranteed operating temperature range for the LTC6930CMS8-4.19#TRPBF?
The LTC6930CMS8-4.19#TRPBF is an I-grade part with a guaranteed operating temperature range of –40°C to +85°C. Performance specifications including frequency accuracy (±0.1%), supply current, and jitter are validated across this full range. It is not rated for extended industrial (–40°C to +125°C) or automotive grades.
How does the LTC6930CMS8-4.19#TRPBF achieve low jitter despite being a silicon oscillator?
The LTC6930CMS8-4.19#TRPBF achieves <0.15% RMS period jitter through a proprietary switched-capacitor feedback loop that stabilizes the master oscillator against temperature and supply variation, combined with dual-supply/dual-ground pin architecture isolating the oscillator core from output driver noise. Its 3ns rise/fall time and 40Ω output impedance further minimize deterministic jitter under capacitive loading.
Can the output frequency of the LTC6930CMS8-4.19#TRPBF be changed dynamically during operation?
Yes, the LTC6930CMS8-4.19#TRPBF supports dynamic frequency reconfiguration. Changing the logic states of DIVA, DIVB, and DIVC pins causes the output to switch to the new divided frequency within one complete output cycle - with no glitches, runt pulses, or undefined states. This allows runtime adaptation for multi-rate communication protocols or power-aware clock scaling.
