Product details
Overview
LTC6930HMS8-5.00#TRPBF from Analog Devices (acquired 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 125°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time - ideal for industrial sensor nodes requiring stable timing under wide temperature and low-voltage conditions.
For engineers reviewing the LTC6930HMS8-5.00#TRPBF datasheet, LTC6930HMS8-5.00#TRPBF pinout, LTC6930HMS8-5.00#TRPBF application, or LTC6930HMS8-5.00#TRPBF equivalent, key selection criteria include its H-grade extended temperature range, MSOP-8 package compatibility, RMS period jitter <0.8ns at 5MHz, and no external components required beyond 0.1µF bypass capacitors.
Technical Context
The LTC6930HMS8-5.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator against voltage and temperature variation. Its three CMOS digital inputs (DIVA/DIVB/DIVC) configure binary division ratios from 1 to 128, enabling precise output frequencies without trimming or calibration.
It features dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate the output driver path from control-loop supply noise, reducing deterministic jitter. The 40Ω CMOS output driver supports ≤50pF capacitive or 1kΩ resistive loads with 3ns rise/fall times and 35–65% duty cycle stability across supply (1.7–5.5V) and divide settings.
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 125°C (LTC6930H grade), enabling single-point calibration in harsh environments |

Pinout & Package
Package: 8-Lead Plastic MSOP (3.00mm × 4.90mm), RoHS-compliant, lead-free finish. Exposed pad not present (MS8 variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pins 1, 8) | Positive supply input | Dual supply pins reduce IR drop and supply noise coupling into oscillator core; each requires local 0.1µF ceramic bypass to adjacent GND |
| GND (Pins 2, 6) | Ground reference | Dual ground pins provide low-inductance return paths; must be connected together and to system ground plane |
| DIVA, DIVB, DIVC (Pins 3, 4, 5) | Binary divider select inputs | CMOS logic inputs (VIH = 1.4V min, VIL = 0.7V max); set division ratio N = 20–7 to select one of eight output frequencies |
| OUT (Pin 7) | CMOS clock output | 40Ω series resistance, 3ns rise/fall time; drives ≤50pF load directly; held low during start-up to prevent glitches |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1533AI-H4-33E-32.768D | 32.768kHz fixed-output MEMS oscillator; ±10ppm initial accuracy; 1.62–3.63V supply | Single-frequency only; lacks programmable division; optimized for RTC backup, not general-purpose clocking | Select when only 32.768kHz is needed and ultra-low power (<1µA) is critical; not suitable for 5MHz system clocks. |
| MAX7375AXR25+T | 25MHz fixed-output silicon oscillator; ±50ppm accuracy over –40°C to 105°C; 1.7–3.6V supply | No frequency selection; higher jitter (1.5ns P-P); limited to commercial temp range | Choose for cost-sensitive consumer applications where 25MHz is acceptable and H-grade operation is unnecessary. |

FAQ
What is the maximum output frequency achievable with the LTC6930HMS8-5.00#TRPBF?
The LTC6930HMS8-5.00#TRPBF has a factory-set master oscillator frequency of 5.000000MHz. When the DIVA/DIVB/DIVC pins are configured as [000], the internal divider is set to ÷1, delivering the full 5.000MHz output. This is the maximum frequency; all other configurations yield lower frequencies (e.g., 2.5MHz at ÷2). No configuration exceeds 5.000MHz.
Does the LTC6930HMS8-5.00#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HMS8-5.00#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 tolerances, PCB layout sensitivity, and aging-related frequency drift inherent in quartz solutions.
How does the LTC6930HMS8-5.00#TRPBF achieve ±0.1% accuracy over –40°C to 125°C?
The LTC6930HMS8-5.00#TRPBF achieves ±0.1% accuracy across its full H-grade temperature range using a proprietary switched-capacitor feedback loop that actively compensates the master oscillator for temperature-induced capacitance shifts. This architecture, combined with factory calibration at multiple temperatures, ensures guaranteed performance without external compensation circuits.
Can the DIV pins of the LTC6930HMS8-5.00#TRPBF be changed dynamically during operation?
Yes, the DIVA/DIVB/DIVC pins of the LTC6930HMS8-5.00#TRPBF can be reconfigured dynamically while powered. The output transitions cleanly to the new frequency within one clock cycle of the final DIV pin change, with no glitches, runt pulses, or metastability - enabling real-time clock scaling in adaptive power management systems.
What is the recommended PCB layout practice for minimizing jitter on the LTC6930HMS8-5.00#TRPBF OUT pin?
To minimize jitter on the LTC6930HMS8-5.00#TRPBF OUT pin, route the output trace away from V+ and GND pins (especially Pin 1 and Pin 2), use a solid ground plane beneath the device, keep the output trace short and impedance-uncontrolled (no 50Ω termination needed), and avoid routing near noisy digital signals. Place the 0.1µF bypass capacitors as close as possible to Pins 1–2 and 6–8 pairs.
