Product details
Overview
LTC6930IMS8-5.00#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set 5.000000MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 39.0625kHz to 5.000MHz. It delivers ±0.1% frequency accuracy over –40°C to 85°C, 105µA typical supply current at 32kHz/3V, <110µs start-up time, and RMS period jitter <0.15% at 3V - ideal for low-power microprocessor clocking in portable instrumentation.
For engineers reviewing the LTC6930IMS8-5.00#TRPBF datasheet, LTC6930IMS8-5.00#TRPBF pinout, LTC6930IMS8-5.00#TRPBF application, or LTC6930IMS8-5.00#TRPBF equivalent, this page provides verified specifications, MS8 package terminal mapping, temperature-stable timing performance, and validated alternatives for battery-powered embedded systems requiring precision without external crystals.
Technical Context
The LTC6930IMS8-5.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator across voltage (1.7V–5.5V) and temperature (–40°C to 85°C). Its three CMOS digital inputs (DIVA/DIVB/DIVC) configure binary division ratios from 1 to 128, enabling eight discrete output frequencies without external components.
Internal dual-supply routing isolates the oscillator core from the output driver, minimizing deterministic jitter. The 40Ω CMOS output driver maintains controlled 3ns rise/fall times and supports up to 50pF capacitive load or 1kΩ resistive load while holding output low during power-up to prevent glitches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 39.0625kHz to 5.000MHz (8 factory-selectable divisions of 5.000000MHz master) |
| Frequency Accuracy | ±0.1% max over –40°C to 85°C at V+ = 3V–3.6V - enables reliable timing without calibration in industrial sensors |

FAQ
What is the maximum output frequency achievable with the LTC6930IMS8-5.00#TRPBF?
The LTC6930IMS8-5.00#TRPBF has a factory-set 5.000000MHz master oscillator. With DIVA/DIVB/DIVC pins configured as [000], the output is ÷1, delivering exactly 5.000MHz. This is the highest frequency available for this part number; no configuration yields higher than 5.000MHz. The device does not support multiplication or fractional division.
Does the LTC6930IMS8-5.00#TRPBF require external load capacitors like quartz oscillators?
No, the LTC6930IMS8-5.00#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are needed. This eliminates crystal matching uncertainty and PCB layout sensitivity inherent in traditional crystal-based solutions.
Can the LTC6930IMS8-5.00#TRPBF operate from a single 1.8V supply?
Yes, the LTC6930IMS8-5.00#TRPBF supports supply voltages from 1.7V to 5.5V. At 1.8V, it delivers 5.000MHz output with typical supply current of 154µA (÷1 setting) and maintains ±0.8% frequency accuracy across the full –40°C to +85°C range - making it suitable for low-voltage microcontroller systems.
How does the LTC6930IMS8-5.00#TRPBF handle switching between frequencies during operation?
The LTC6930IMS8-5.00#TRPBF switches frequencies glitch-free within one output clock cycle when DIVA/DIVB/DIVC states change. The output remains valid and monotonic - no runt pulses, slivers, or undefined states occur. This behavior is verified in the datasheet's "Typical Output Waveform at DIV Pin Change" plot and enables safe dynamic clock scaling in firmware.
What is the long-term frequency stability specification for the LTC6930IMS8-5.00#TRPBF?
The LTC6930IMS8-5.00#TRPBF has a typical long-term frequency stability of 30ppm/√kHr, measured at 30°C under nominal operating conditions. Over five years (43.83kHr), this translates to ≈0.0198% drift (198ppm) assuming continuous operation. Drift without power applied is approximately one-tenth of this value, or ~3ppm/√kHr.
