Product details
Overview
LTC6930HDCB-8.19#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled, precision silicon oscillator delivering factory-set 8.192MHz master frequency with user-selectable divide-by-1 to 128 outputs (64kHz to 8.192MHz), ±0.1% max frequency accuracy over –40°C to 125°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time. It serves as a low-power timing reference in battery-operated industrial sensors and automotive body controllers.
For engineers reviewing the LTC6930HDCB-8.19#TRPBF datasheet, LTC6930HDCB-8.19#TRPBF pinout, LTC6930HDCB-8.19#TRPBF application, or LTC6930HDCB-8.19#TRPBF equivalent, key selection criteria include its H-grade extended temperature operation, DFN-8 (2mm × 3mm) package with exposed thermal pad, digital DIV pin control architecture, and RMS period jitter <0.8ps at 8.192MHz.
Technical Context
The LTC6930HDCB-8.19#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 8.192MHz master oscillator across voltage and temperature. Its three CMOS DIV pins (DIVA/DIVB/DIVC) configure binary division ratios (1–128) without external components, enabling eight discrete output frequencies from 64kHz to 8.192MHz.
It features dual V+ pins (1,8) and dual GND pins (2,6) to isolate oscillator core from output driver noise, and a 40Ω CMOS output driver with 3ns rise/fall time (10–90%) optimized for 5pF load. The exposed pad (Pin 9) must be soldered to GND for thermal and electrical performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 64kHz to 8.192MHz via DIV pin selection; enables precise clocking for microcontrollers and ADCs without crystal load tuning. |
| Frequency Accuracy | ±0.1% max over –40°C to 125°C; ensures reliable timing in harsh automotive and industrial environments. |
| Supply Current | 190µA typical at 8.192MHz/3V; supports multi-year battery life in low-duty-cycle IoT sensors. |
| Start-Up Time | <110µs to first valid cycle; critical for fast wake-up in energy-harvesting systems. |
| RMS Period Jitter | 0.8ps at 8.192MHz/3V; meets jitter requirements for high-resolution SAR ADC sampling clocks. |
| Operating Voltage | 1.7V to 5.5V single supply; compatible with Li-ion, 2xAA, and wide-input industrial rails. |
| Package | 8-lead DFN (2mm × 3mm) with exposed thermal pad; enables compact PCB layout in space-constrained modules. |
Pinout & Package
Package: 8-lead plastic DFN (2mm × 3mm), exposed pad (Pin 9) required to be soldered to GND for thermal management and signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive supply input | Dual supply pins reduce power delivery impedance; each requires local 0.1µF bypass to adjacent GND pin. |
| GND (Pins 2, 6) | Ground reference | Dual ground pins provide low-inductance return path; must be connected to exposed pad and shared ground plane. |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Digital frequency divider select | CMOS inputs (VIH = 1.4V min, VIL = 0.7V max); set binary divisor N = 2(4×DIVC + 2×DIVB + DIVA) for 1–128 division. |
| OUT (Pin 7) | CMOS clock output | 40Ω series resistance; drives ≤50pF capacitive or 1kΩ resistive loads; held low during start-up to prevent glitches. |
| Exposed Pad (Pin 9) | Thermal and electrical ground | Must be soldered to PCB GND plane; improves thermal dissipation and reduces output jitter by lowering ground impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Digitally programmable frequency | 8 discrete output frequencies (64kHz–8.192MHz) selected via 3-pin binary code-no external crystals or trimming components needed. |
| Extended temperature grade | H-grade rating (–40°C to 125°C) validated for under-hood automotive and industrial control applications without derating. |
| Ultralow power consumption | 105µA typical at 32kHz/3V enables >10-year battery life in wireless sensor nodes with 1-second wake intervals. |
| Clean output switching | No runt pulses or glitches during DIV pin changes; output settles within one clock cycle for deterministic timing in reconfigurable systems. |
| Integrated supply regulation | Internal regulation maintains <0.07%/V frequency drift over 1.7V–5.5V supply range-eliminates need for external LDO in multi-rail systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1533AI-H4-33E-8.192000G | MEMS-based; ±10ppm initial accuracy (±0.001%); higher cost; 1.62–3.63V supply. | Better accuracy and lower jitter but limited to 3.63V max; not suitable for 5V industrial rails. | Select when sub-10ppm accuracy and ultra-low jitter (<0.5ps) are mandatory, and supply voltage is ≤3.63V. |
| DS3231M#T&R | Temperature-compensated crystal oscillator (TCXO); ±2ppm over –40°C to +85°C; 3.3V only; I²C interface. | Superior long-term stability but lacks digital frequency selection; requires I²C host control. | Select when highest aging stability (<±1ppm/year) is required and system has I²C resources for configuration. |
Compared with SiT1533AI-H4-33E-8.192000G and DS3231M#T&R, the LTC6930HDCB-8.19#TRPBF offers broader supply range (1.7–5.5V), integrated digital frequency selection without communication bus overhead, and H-grade temperature support-making it optimal for cost-sensitive, wide-voltage industrial controllers where ±0.1% accuracy suffices.

FAQ
What is the maximum operating temperature for LTC6930HDCB-8.19#TRPBF?
The LTC6930HDCB-8.19#TRPBF is rated for continuous operation from –40°C to +125°C, verified per its H-grade specification. This makes it suitable for under-hood automotive applications and industrial equipment exposed to high ambient temperatures. The device's frequency accuracy remains within ±0.1% across this full range when powered from 1.7V to 5.5V.
How do I configure LTC6930HDCB-8.19#TRPBF to output 4.096MHz?
To output 4.096MHz, set DIVA = HIGH, DIVB = LOW, DIVC = LOW (binary 001), which configures the internal divider to ÷2. Since the LTC6930HDCB-8.19#TRPBF's master oscillator is factory-set to 8.192MHz, dividing by 2 yields exactly 4.096MHz. Connect DIVA to V+, and tie DIVB/DIVC to GND using appropriate pull-down resistors or direct connections.
Does LTC6930HDCB-8.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HDCB-8.19#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors. Only 0.1µF ceramic bypass capacitors between each V+ pin (1,8) and its adjacent GND pin (2,6) are needed. The output drives up to 50pF directly, eliminating crystal matching networks and reducing BOM count.
What is the typical supply current of LTC6930HDCB-8.19#TRPBF at 8.192MHz and 3V?
At 8.192MHz output and V+ = 3V, the LTC6930HDCB-8.19#TRPBF draws 190µA typical supply current (with all DIV pins low, i.e., ÷1 mode). This value increases slightly with higher load capacitance or supply voltage but remains below 500µA across its full operating range, supporting ultra-low-power system design.
Can LTC6930HDCB-8.19#TRPBF be used as a drop-in replacement for a 8.192MHz crystal oscillator?
The LTC6930HDCB-8.19#TRPBF is not a pin-compatible drop-in replacement for a 2-pin crystal; it is an active 8-pin oscillator requiring connection to DIV pins and dual supply/ground paths. However, it replaces the entire crystal + load capacitor + startup circuit, simplifying layout and improving reliability-especially in high-vibration environments where crystals may fail.
