Product details
Overview
LTC6930IMS8-7.37#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set 7.3728MHz master frequency, selectable via DIVA/DIVB/DIVC pins across 8 output frequencies (57.6kHz–7.3728MHz), ±0.1% frequency accuracy over –40°C to 85°C, 1.7V–5.5V supply, and 110µs start-up time. It serves as a precision timing source in battery-powered microcontroller clocking and portable instrumentation.
For engineers reviewing the LTC6930IMS8-7.37#TRPBF datasheet, LTC6930IMS8-7.37#TRPBF pinout, LTC6930IMS8-7.37#TRPBF application, or LTC6930IMS8-7.37#TRPBF equivalent, key selection criteria include its ±0.1% temperature-stable accuracy, 105µA typical current at 32kHz/3V, MS8 package compatibility, and digital frequency selection without external components.
Technical Context
The LTC6930IMS8-7.37#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its 7.3728MHz master oscillator against temperature and supply variation. Its internal binary divider (1–128) is controlled by three CMOS logic inputs (DIVA/DIVB/DIVC), enabling deterministic frequency selection without trimming or calibration.
It features dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate the oscillator core from output switching noise, achieving <0.15% RMS period jitter at 3V and maintaining clean output waveform integrity during DIV pin transitions - critical for low-jitter system clocking in mixed-signal environments.
Key Specifications

|---|---|
| Output Frequency Range | 57.6kHz to 7.3728MHz (8 factory-selectable divisions of 7.3728MHz master) |
| Frequency Accuracy | ±0.1% max over –40°C to 85°C, enabling reliable timing without external crystal or calibration |
| Supply Voltage | 1.7V to 5.5V single supply - supports direct operation from Li-ion or dual AA cells |
| Start-Up Time | <110µs to first valid output cycle - minimizes wake-up latency in duty-cycled systems |
| Supply Current | 183µA typical at 7.3728MHz/3V; 139µA at 32kHz/1.7V - enables multi-year battery life in low-duty-cycle sensors |

Pinout & Package
Package: 8-Lead Plastic MSOP (MS8), 3mm × 3mm body, 0.65mm pitch, exposed thermal pad not present (MSOP variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive Supply Input | Dual supply pins reduce PSRR coupling; 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 |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Digital Frequency Select Inputs | CMOS logic inputs (VIH = 1.4V min); set 3-bit binary divider (1–128) per Table 1 |
| OUT (Pin 7) | CMOS Clock Output | 40Ω series resistance; drives ≤50pF load; held low during start-up to prevent glitches |
Key Features
| Feature | Design Value |
|---|---|
| Digital frequency selection | Eliminates need for external crystals, load capacitors, or trimming components - reduces BOM count and layout area |
| Ultralow power at low frequencies | 105µA typical at 32kHz/3V enables decade-long operation in coin-cell-powered real-time clocks |
| Fast, glitch-free DIV switching | Output updates within one clock cycle without runt pulses - safe for dynamic clock scaling in firmware |
| Supply-regulated frequency stability | 0.07%/V drift ensures consistent timing across battery discharge voltage range (e.g., 3.3V → 2.7V) |
| Factory-programmed master oscillator | 7.3728MHz base frequency optimized for UART baud rate generation (e.g., 115.2kbps, 230.4kbps) |

FAQ
What is the nominal master oscillator frequency of the LTC6930IMS8-7.37#TRPBF?
The LTC6930IMS8-7.37#TRPBF has a factory-programmed master oscillator frequency of exactly 7.372800MHz. This value is fixed and non-adjustable; all eight output frequencies (57.6kHz to 7.3728MHz) are derived via integer division (1–128) using the DIVA/DIVB/DIVC pins. The part number suffix "-7.37" explicitly denotes this master frequency.
Does the LTC6930IMS8-7.37#TRPBF require external load capacitors like a quartz crystal?
No, the LTC6930IMS8-7.37#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 (1 and 8) and its adjacent GND pin (2 and 6) are needed for stable operation. This eliminates component count, layout sensitivity, and crystal aging concerns inherent in traditional crystal-based solutions.
What is the maximum capacitive load the OUT pin of the LTC6930IMS8-7.37#TRPBF can drive?
The OUT pin of the LTC6930IMS8-7.37#TRPBF is specified to drive up to 50pF capacitive load or 1kΩ resistive load. Its typical output resistance is 40Ω at 3V supply. Driving loads >5pF increases supply current proportionally (ISUPPLY ≈ CLOAD × VSWING × fOSC); for example, a 50pF load at 7.3728MHz draws ~2.7mA additional average current beyond the base oscillator consumption.
Can the LTC6930IMS8-7.37#TRPBF operate from a single 1.7V supply?
Yes, the LTC6930IMS8-7.37#TRPBF is fully functional across 1.7V to 5.5V. At 1.7V, it delivers 139µA typical supply current at 32kHz output and maintains ±0.1% frequency accuracy over –40°C to 85°C. This makes it suitable for deep-discharge battery operation, such as in two-AA or single-LiFePO₄ systems where voltage drops below 2.0V.
How does the LTC6930IMS8-7.37#TRPBF achieve ±0.1% frequency accuracy without calibration?
The LTC6930IMS8-7.37#TRPBF achieves ±0.1% accuracy using a proprietary switched-capacitor feedback loop that actively stabilizes its 7.3728MHz master oscillator against temperature, supply, and process variation. Unlike quartz devices, it does not rely on mechanical resonance but on calibrated on-chip RC timing and digital correction - enabling factory-trimmed accuracy without post-assembly calibration or external components.
