Product details
Overview
LTC6930CDCB-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 0°C to 70°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 battery-powered microcontroller systems.
For engineers reviewing the LTC6930CDCB-4.19#TRPBF datasheet, LTC6930CDCB-4.19#TRPBF pinout, LTC6930CDCB-4.19#TRPBF application, or LTC6930CDCB-4.19#TRPBF equivalent, key selection criteria include initial frequency error, supply current vs. divider setting, temperature stability across DCB package, and digital control interface timing for low-power embedded timing.
Technical Context
The LTC6930CDCB-4.19#TRPBF integrates a factory-trimmed master oscillator (4.194304MHz) with a digitally selectable binary divider (1–128) controlled by three CMOS logic inputs (DIVA/DIVB/DIVC), enabling eight discrete output frequencies from 32.768kHz to 4.194304MHz. Its proprietary switched-capacitor feedback loop maintains frequency stability against voltage and temperature variation.
It operates from a single 1.7V–5.5V supply, requires no external timing components beyond 0.1µF bypass capacitors, and features an isolated dual-V+ architecture (Pins 1 & 8) and dual-GND (Pins 2 & 6) to minimize coupling between control circuitry and output driver - critical for low-jitter performance in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency | 4.194304MHz - fixed master oscillator frequency; output derived via integer division (÷1 to ÷128). |
| Frequency Accuracy | ±0.1% max over 0°C to 70°C - ensures reliable timing margin for UART, SPI, and real-time clock synchronization. |
| Supply Current | 105µA typical at 32kHz/3V; 490µA typical at 4.194MHz/3V - enables multi-year operation on coin-cell batteries. |
| Start-Up Time | <110µs - supports rapid wake-from-sleep cycles in duty-cycled sensor nodes and wearables. |
| RMS Period Jitter | <0.15% at V+ = 3V - translates to ~180ps RMS jitter at 4.194MHz, sufficient for ADC sampling clocks and low-speed USB interfaces. |
| Output Drive | CMOS-compatible, 40Ω series resistance at 3V - drives 5pF load directly; supports 1kΩ resistive or ≤50pF capacitive loads without external buffering. |
| Operating Temp | 0°C to 70°C (Commercial grade) - validated for industrial control panels and consumer electronics enclosures. |
Pinout & Package
Package: 8-lead (2mm × 3mm) plastic DFN (DCB), exposed thermal pad (Pin 9) required to be soldered to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive supply input | Dual supply pins reduce supply impedance; each must be bypassed to adjacent GND with 0.1µF ceramic capacitor. |
| GND (Pins 2, 6) | Ground reference | Dual ground pins provide low-inductance return path; both must connect to same PCB ground plane and exposed pad. |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Digital frequency select inputs | CMOS logic inputs (VIH ≥ 1.25V, VIL ≤ 1.25V); set divider ratio (1–128) per Table 1; no pull-ups required. |
| OUT (Pin 7) | CMOS clock output | Push-pull output with 2ns rise/fall time; held low during power-up; glitch-free transition on DIV pin changes. |
| Exposed Pad (Pin 9) | Thermal & electrical ground | Must be soldered to solid GND plane; improves thermal dissipation and reduces ground bounce-induced jitter. |
Key Features
| Feature | Design Value |
|---|---|
| Digitally programmable output | Eight precise frequencies (32.768kHz–4.194MHz) selected via 3-pin binary code - eliminates need for multiple crystal SKUs in BOM. |
| Ultralow power operation | 105µA at 32kHz enables >10-year battery life in always-on RTC applications using CR2032 cells. |
| Factory-trimmed accuracy | ±0.1% max initial error over commercial temp range - meets requirements for USB audio clocking and serial communication without calibration. |
| Fast, glitch-free start-up | <110µs start-up with output held low until stable - prevents spurious MCU resets or peripheral lock-up during wake-up. |
| No external components | Operates with only two 0.1µF bypass caps - reduces PCB area, BOM count, and assembly cost versus crystal + load cap solutions. |

FAQ
What is the nominal output frequency of the LTC6930CDCB-4.19#TRPBF?
The LTC6930CDCB-4.19#TRPBF is factory-programmed with a nominal master oscillator frequency of 4.194304MHz. Its output frequency is determined by internal division (÷1 to ÷128) selected via DIVA/DIVB/DIVC pins. When all DIV pins are low (000), the output is exactly 4.194304MHz - confirmed in the datasheet's Frequency Setting Table 1 and AC Electrical Characteristics section.
Does the LTC6930CDCB-4.19#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930CDCB-4.19#TRPBF does not require external load capacitors. It is a fully integrated silicon oscillator with internal frequency generation and regulation. Only two 0.1µF ceramic bypass capacitors (one between each V+ pin and its adjacent GND pin) are required - explicitly stated in the Applications Information and Pin Functions sections of the datasheet.
What is the maximum operating temperature range for the LTC6930CDCB-4.19#TRPBF?
The LTC6930CDCB-4.19#TRPBF is rated for 0°C to 70°C (Commercial temperature grade), as specified in the Order Information table and Specified Temperature Range note. This differs from the I-grade (–40°C to 85°C) and H-grade (–40°C to 125°C) variants - the "C" suffix in the part number confirms the commercial range.
How does the LTC6930CDCB-4.19#TRPBF achieve low jitter despite being a silicon oscillator?
The LTC6930CDCB-4.19#TRPBF achieves <0.15% RMS period jitter through a proprietary switched-capacitor feedback loop that stabilizes the master oscillator against voltage and temperature variation, combined with dual isolated supply/ground paths (Pins 1/8 and 2/6) to minimize coupling between control circuitry and output driver - detailed in the Theory of Operation and Applications Information sections.
Can the LTC6930CDCB-4.19#TRPBF operate from a single 1.8V supply?
Yes, the LTC6930CDCB-4.19#TRPBF supports supply voltages from 1.7V to 5.5V, including 1.8V. At 1.8V and 4.194MHz output (DIV=1), typical supply current is 290µA (per DC Electrical Characteristics table), and frequency accuracy remains within ±0.8% over full voltage range - making it suitable for low-voltage IoT sensor nodes.
