Product details
Overview
LTC6930IMS8-8.19#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 (64kHz to 8.192MHz), ±0.1% frequency accuracy over –40°C to 85°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time. It serves as a low-power timing source in battery-operated microcontroller systems requiring stable clocking without external crystals.
For engineers reviewing the LTC6930IMS8-8.19#TRPBF datasheet, LTC6930IMS8-8.19#TRPBF pinout, LTC6930IMS8-8.19#TRPBF application, or LTC6930IMS8-8.19#TRPBF equivalent, key selection criteria include its 8-pin MSOP package, DIVA/DIVB/DIVC digital frequency control interface, RMS period jitter <0.8ps at 8.192MHz, and operation from 1.7V to 5.5V single supply.
Technical Context
The LTC6930IMS8-8.19#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize a factory-trimmed master oscillator (8.192MHz), enabling <0.09% initial frequency error at 25°C. Its internal binary divider (N = 1–128) is selected via three CMOS logic inputs (DIVA/DIVB/DIVC), producing eight discrete output frequencies without external components.
Supply regulation and dual V+/GND pin pairs isolate the control loop from output driver noise, achieving typical RMS period jitter of 0.8ps at 8.192MHz and deterministic glitch-free transitions when changing DIV settings - critical for real-time embedded timing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 64kHz to 8.192MHz (factory-set 8.192MHz master + /1–/128 divider) |
| Frequency Accuracy | ±0.1% max over –40°C to 85°C (LTC6930I grade) |
| Supply Voltage | 1.7V to 5.5V single supply - supports Li-ion or dual AA battery operation |
| Supply Current | 190µA typical at 8.192MHz/3V; 150µA at 32.768kHz/3V |
| RMS Period Jitter | 0.8ps at 8.192MHz/3V - enables clean timing for high-speed digital interfaces |

Pinout & Package
Package: 8-lead plastic MSOP (MS8), 3mm × 4.9mm footprint, exposed pad not present (unlike DFN variant). Pin 1 marked by notch; pins 1/8 = V+, 2/6 = GND, 3 = DIVA, 4 = DIVB, 5 = DIVC, 7 = OUT.
| 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 | Low-inductance return path shared across analog/digital sections; must be connected together |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Digital frequency select inputs | CMOS logic inputs (VIH ≥1.25V, VIL ≤1.25V); set /1–/128 divider ratio per Table 1 |
| OUT (Pin 7) | CMOS clock output | 40Ω series resistance; drives ≤50pF capacitive or 1kΩ resistive load; held low during start-up |
Key Features
| Feature | Design Value |
|---|---|
| No external timing components required | Self-contained silicon oscillator eliminates crystal, load caps, and matching network - reduces BOM and layout area |
| Ultralow power consumption | 150µA at 32.768kHz/3V enables multi-year battery life in RTC and sensor nodes |
| Deterministic DIV pin switching | Output updates within one clock cycle without runt pulses or glitches - safe for dynamic clock scaling |
| High immunity to supply noise | Internal regulation limits frequency drift to 0.07%/V - maintains timing accuracy in noisy power domains |
| Fast, monotonic start-up | <110µs to stable output with no overshoot or frequency slewing - simplifies power sequencing |

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 fixed-output MEMS oscillator; ±10ppm stability; no digital divider; 1.62–3.63V supply | Only provides 32.768kHz - lacks programmable divide capability and 8.192MHz base frequency | Select when only RTC-grade 32.768kHz is needed and digital frequency selection is unnecessary |
| MAX7375ETE+ | 3-output programmable clock generator; supports 1–170MHz; requires external crystal; 2.97–5.5V supply | Requires external 10MHz crystal; higher quiescent current (2mA typical); larger 16-pin TQFN package | Select when multiple synchronized clocks or wider frequency range is required, accepting higher power and external component cost |

FAQ
What is the maximum output frequency achievable with the LTC6930IMS8-8.19#TRPBF?
The LTC6930IMS8-8.19#TRPBF has a factory-programmed master oscillator frequency of 8.192MHz. When configured with DIVA=DIVB=DIVC=0 (divide-by-1), the output frequency is exactly 8.192MHz - its maximum possible output. This value is confirmed in Table 1 of the datasheet and applies across the full operating temperature and supply voltage range.
Does the LTC6930IMS8-8.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930IMS8-8.19#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or crystals. Only 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 (Figure 1) and Applications Information section.
What is the guaranteed frequency accuracy of the LTC6930IMS8-8.19#TRPBF over temperature?
The LTC6930IMS8-8.19#TRPBF carries the "I" temperature grade, guaranteeing ±0.1% frequency accuracy over the full –40°C to 85°C operating range when V+ = 3V–3.6V. At wider supply ranges (1.7V–5.5V), accuracy degrades to ±0.8% max - both values are explicitly listed in the AC Electrical Characteristics table under Δf parameter.
Can the LTC6930IMS8-8.19#TRPBF drive a 50pF capacitive load reliably?
Yes, the LTC6930IMS8-8.19#TRPBF output driver is rated for up to 50pF capacitive load. Its typical series resistance is 40Ω at 3V, and supply current increases predictably with load capacitance (e.g., ~2.2mA at 8.192MHz/50pF/5.5V swing). The datasheet confirms this capability in the Output Driver and Loading section and Typical Performance Characteristics (Figure G05).
How does the LTC6930IMS8-8.19#TRPBF handle changes to the DIVA/DIVB/DIVC pins during operation?
The LTC6930IMS8-8.19#TRPBF responds to DIV pin changes within one clock cycle of the new setting, with no glitches, runt pulses, or frequency transients - as verified in the Switching the DIV Pins section and Figure G18 (Typical Output Waveform at DIV Pin Change). This deterministic behavior enables safe dynamic clock scaling in real-time systems.
