Product details
Overview
LTC6930HMS8-5.00#PBF from Analog Devices (formerly Linear Technology) is a digitally controlled, precision 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 125°C, consumes only 124µA typical at 3V/5MHz, and features <110µs power-on delay - ideal for industrial sensor nodes and high-reliability embedded timing.
For engineers reviewing the LTC6930HMS8-5.00#PBF datasheet, LTC6930HMS8-5.00#PBF pinout, LTC6930HMS8-5.00#PBF application, or LTC6930HMS8-5.00#PBF equivalent, this page provides verified specifications, MS8 package terminal mapping, temperature-stable jitter performance (<0.15% RMS period jitter at 3V), and validated alternatives for automotive-grade microcontroller clocking and battery-powered instrumentation.
Technical Context
The LTC6930HMS8-5.00#PBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator against supply and temperature variation. Its three digital DIV inputs control an integer divider (1–128) to generate eight precise output frequencies without external components.
It uses dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate the oscillator core from output switching noise, enabling clean CMOS output (40Ω series resistance, 3ns rise/fall time) even under 50pF capacitive load - critical for low-jitter timing in mixed-signal systems operating from 1.7V to 5.5V.
Key Specifications

| DIVB (Pin 4) | Frequency Divider Control | CMOS input; middle bit of divider select; state determines output division ratio per Table 1 |
| DIVC (Pin 5) | Frequency Divider Control | CMOS input; MSB of divider select; all three pins define one of eight factory-programmed output frequencies |
| OUT (Pin 7) | CMOS Clock Output | Low-impedance (40Ω typ) push-pull driver; holds low during start-up; glitch-free on DIV changes |
Key Features
| Feature | Design Value |

FAQ
What is the maximum output frequency achievable with LTC6930HMS8-5.00#PBF?
The LTC6930HMS8-5.00#PBF has a factory-set 5.000000MHz master oscillator. When DIVA=DIVB=DIVC=0 (÷1 setting), the output frequency is exactly 5.000MHz - the highest frequency available for this variant. No internal multiplication is supported; all outputs are integer divisions of the master frequency.
Does LTC6930HMS8-5.00#PBF require external load capacitors like quartz crystals?
No. The LTC6930HMS8-5.00#PBF 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 - eliminating crystal matching uncertainty and PCB layout sensitivity inherent in discrete crystal designs.
Can LTC6930HMS8-5.00#PBF operate from a single 1.8V supply?
Yes. The LTC6930HMS8-5.00#PBF is specified for 1.7V to 5.5V operation. At 1.8V supply, 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 125°C range - suitable for low-voltage microcontrollers and wearables.
How does the LTC6930HMS8-5.00#PBF achieve ±0.1% accuracy over temperature?
The LTC6930HMS8-5.00#PBF uses a proprietary switched-capacitor feedback loop that continuously corrects the master oscillator's frequency in response to temperature-induced capacitance shifts. This active stabilization - combined with factory trimming and H-grade process characterization - achieves ±0.1% total error from –40°C to 125°C without external compensation circuitry.
Is the OUT pin of LTC6930HMS8-5.00#PBF 5V-tolerant when powered from 3.3V?
No. The OUT pin is a CMOS push-pull driver referenced to the V+ supply. When V+ = 3.3V, VOH is typically 3.0V (min 2.6V with 1kΩ load), and VOL is typically 0.1V (max 0.3V). It is not 5V-tolerant; connecting to 5V logic without level shifting may cause excessive current or damage.
