Product details
Overview
LTC6930IDCB-8.00#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator delivering factory-programmed 8.000000MHz output with ±0.1% frequency accuracy over –40°C to +85°C, 1.7V–5.5V supply, and <110µs start-up time. It uses internal binary dividers (1–128) to generate eight selectable frequencies down to 62.5kHz and targets microprocessor clocking, portable device timing, and low-power embedded systems.
For engineers reviewing the LTC6930IDCB-8.00#TRPBF datasheet, LTC6930IDCB-8.00#TRPBF pinout, LTC6930IDCB-8.00#TRPBF application, or LTC6930IDCB-8.00#TRPBF equivalent, key selection criteria include initial frequency error (<0.09% typ), RMS period jitter (<0.8nsP-P at 8MHz), supply current scalability across DIV settings, DFN package thermal performance, and digital frequency control via three CMOS input pins.
Technical Context
The LTC6930IDCB-8.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its factory-set 8.000000MHz master oscillator against temperature and supply variation. Its control architecture enables ultralow power operation while maintaining <0.1% max frequency drift over full operating temperature range.
Frequency selection is achieved through three digital inputs (DIVA/DIVB/DIVC) that configure an internal binary divider (N = 1 to 128), producing eight precise output frequencies from 8.000MHz down to 62.5kHz. The output driver features 40Ω series resistance, 3ns rise/fall time, and glitch-free switching during DIV pin transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 8.000000MHz - fixed master oscillator frequency; output derived via integer division (÷1 to ÷128). |
| Initial Accuracy | ±0.09% max at 25°C - ensures timing-critical systems meet startup frequency tolerance without calibration. |
| Temp Range | –40°C to +85°C - industrial-grade operation verified across full range per LTC6930I specification. |
| Supply Current | 491µA typ at 3V, ÷1 setting - enables battery life extension in duty-cycled applications. |
| RMS Period Jitter | 0.8nsP-P at 8MHz - supports clean clocking for ADC sampling, serial interfaces, and MCU peripherals. |

| Output Drive | 40Ω series resistance - minimizes signal reflections and EMI when driving 5pF–50pF loads. |
Pinout & Package
Package: 8-lead (2mm × 3mm) plastic DFN (DCB) with exposed pad soldered to GND. Pin 9 (exposed pad) is electrically connected to ground and required for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive Supply Input | Dual supply pins reduce supply noise coupling; each requires local 0.1µF ceramic bypass to adjacent GND. |
| GND (Pins 2, 6) | Ground Reference | Two dedicated ground pins improve return path integrity; must be connected to common GND plane and exposed pad. |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Digital Frequency Control Inputs | CMOS logic inputs (VIH ≥1.25V, VIL ≤1.25V); set divider ratio N = 1–128 per Table 1; no pull-ups required. |
| OUT (Pin 7) | CMOS Clock Output | Low-impedance buffered output; holds low during start-up; glitch-free on DIV changes; drives 5pF load at 8MHz with 491µA supply current. |
Key Features
| Feature | Design Value |
|---|---|
| Digital frequency selection | Three-pin binary interface selects one of eight precise output frequencies (8MHz to 62.5kHz) without external components. |
| Ultralow power operation | 491µA typical supply current at 8MHz/3V enables multi-year battery life in intermittent-use devices. |
| Factory-trimmed accuracy | ±0.09% initial error eliminates need for post-silicon calibration in cost-sensitive timing applications. |
| Fast, glitch-free start-up | <110µs start-up with held-low output prevents invalid clock edges during system initialization. |
| Robust supply rejection | 0.07%/V frequency drift over 1.7V–5.5V allows direct Li-ion or dual-AA battery operation without regulation. |

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-HR-33E-8.000000D | MEMS-based; ±10ppm initial accuracy; 1.62–3.63V supply; 3.2×2.5mm LGA package. | Higher initial accuracy but wider supply range; lacks digital DIV control-fixed 8MHz output only. | Select for ultra-stable crystal-equivalent performance where programmability is unnecessary and board space permits larger footprint. |
| MAX7375EKA+T | Crystal oscillator IC; requires external 8MHz crystal; ±50ppm accuracy; 1.71–3.6V supply; SOT23-6 package. | Lower accuracy and higher component count; no digital frequency selection; limited to single output frequency. | Select when crystal-based stability is mandated and cost-per-unit favors discrete crystal + oscillator IC over integrated silicon solution. |

FAQ
What is the nominal output frequency of the LTC6930IDCB-8.00#TRPBF?
The LTC6930IDCB-8.00#TRPBF is factory-programmed for a nominal master oscillator frequency of 8.000000MHz. Its output frequency is determined by internal binary division (N = 1 to 128) selected via DIVA/DIVB/DIVC pins, yielding eight possible outputs from 8.000MHz down to 62.5kHz. The "8.00" in the part number explicitly denotes this base frequency.
Does the LTC6930IDCB-8.00#TRPBF require external components for basic operation?
No, the LTC6930IDCB-8.00#TRPBF requires no external timing components. Only two 0.1µF ceramic bypass capacitors-one between each V+ pin (1 and 8) and its adjacent GND pin (2 and 6)-are needed for stable operation. No crystal, load capacitors, or resistors are required, simplifying layout and reducing BOM count.
What is the operating temperature range certified for the LTC6930IDCB-8.00#TRPBF?
The LTC6930IDCB-8.00#TRPBF carries the "I" grade designation, certifying guaranteed performance over –40°C to +85°C. This includes all electrical specifications such as frequency accuracy (±0.1% max), supply current, and jitter across the full range. The DFN package's thermal characteristics support reliable operation within this industrial temperature envelope.
How does the LTC6930IDCB-8.00#TRPBF achieve low frequency drift over supply voltage variation?
The LTC6930IDCB-8.00#TRPBF incorporates an internal regulated supply for its oscillator core, limiting frequency drift to just 0.07%/V over 1.7V–5.5V. This enables direct connection to unregulated battery sources-such as single Li-ion (2.7–4.2V) or dual AA cells (2.0–3.2V)-without compromising timing accuracy, unlike many competing oscillators requiring tight supply regulation.
Can the LTC6930IDCB-8.00#TRPBF be used as a drop-in replacement for quartz crystal oscillators?
The LTC6930IDCB-8.00#TRPBF is not a pin-compatible drop-in replacement for standard XO modules due to different pin count (8-pin DFN vs 4-pin XO) and digital control interface. However, it replaces crystal + buffer + divider solutions in systems needing programmable frequency, faster start-up, and better shock/vibration immunity-offering functional equivalence with simplified design integration.
