Product details
Overview
LTC6930CMS8-8.19#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set master frequency of 8.192MHz, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 64kHz to 8.192MHz. It delivers ±0.1% max frequency accuracy over –40°C to 85°C, 105µA typical supply current at 32kHz/3V, and <110µs start-up time - ideal for low-power microcontroller clocking in portable medical sensors.
For engineers reviewing the LTC6930CMS8-8.19#TRPBF datasheet, LTC6930CMS8-8.19#TRPBF pinout, LTC6930CMS8-8.19#TRPBF application, or LTC6930CMS8-8.19#TRPBF equivalent, this page provides verified specifications, MS8 package terminal mapping, real-world timing roles, and validated alternative options for battery-powered embedded systems requiring stable, jitter-controlled clock sources.
Technical Context
The LTC6930CMS8-8.19#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 8.192MHz master oscillator against temperature and supply variation. Its three CMOS digital inputs (DIVA/DIVB/DIVC) configure binary dividers (1–128) to generate precise output frequencies without external components.
It features dual V+ pins (1 & 8) and dual GND pins (2 & 6) to isolate power delivery from the output driver, minimizing deterministic jitter. The 40Ω CMOS output drives up to 50pF load with 3ns rise/fall time and 50% ±15% duty cycle, maintaining RMS period jitter <0.15% at 3V.
Key Specifications

| GND (Pins 2, 6) | Ground Reference | Dual ground pins minimize return-path inductance; must be tied together on PCB |
| OUT (Pin 7) | CMOS Clock Output | 40Ω driver capable of 50pF load; held low during start-up to prevent runt pulses |
| DIVA (Pin 3) | Frequency Divider Control | LSB of 3-bit binary divider select (000 = ÷1, 111 = ÷128); CMOS input, VIH ≥1.25V |
| DIVB (Pin 4) | Frequency Divider Control | Mid-bit of 3-bit divider select; threshold-matched with DIVA/DIVC for glitch-free switching |
| DIVC (Pin 5) | Frequency Divider Control | MSB of 3-bit divider select; transitions cause output update within one clock cycle |
Key Features
| Feature | Design Value |

FAQ
What is the maximum capacitive load the LTC6930CMS8-8.19#TRPBF output can drive reliably?
The LTC6930CMS8-8.19#TRPBF output is specified to drive up to 50pF capacitive load with maintained jitter and rise/fall time performance. At 8.192MHz and 3V supply, driving 50pF increases supply current to ~2.2mA (calculated as CLOAD × VSWING × fOSC). For loads >5pF, ensure local 0.1µF bypass capacitors are placed at both V+ pins to suppress supply transients caused by output switching.
Can the LTC6930CMS8-8.19#TRPBF operate from a single 1.8V supply?
Yes, the LTC6930CMS8-8.19#TRPBF operates across 1.7V to 5.5V, including 1.8V nominal supplies. At 1.8V and 8.192MHz, typical supply current is 270µA (per DC Electrical Characteristics table). Output voltage swing scales with supply: VOH ≈ 1.5V and VOL ≈ 0.3V into 1kΩ load, ensuring compatibility with 1.8V logic families.
How does the LTC6930CMS8-8.19#TRPBF achieve ±0.1% frequency accuracy without external calibration?
The LTC6930CMS8-8.19#TRPBF achieves ±0.1% accuracy using a factory-trimmed master oscillator with a proprietary switched-capacitor feedback loop that compensates for process, voltage, and temperature variations. This architecture eliminates reliance on external crystals while maintaining stability over –40°C to 85°C without user calibration or temperature sensing circuitry.
Is the LTC6930CMS8-8.19#TRPBF pin-compatible with other LTC6930 variants in MS8 packaging?
Yes, all LTC6930 variants in the MS8 package (e.g., LTC6930IMS8-8.19#TRPBF, LTC6930CMS8-4.19#TRPBF) share identical pinout, footprint, and electrical interface. Only the factory-programmed master frequency differs; DIV pin behavior and timing specs remain consistent across the family.
What is the long-term frequency stability specification for the LTC6930CMS8-8.19#TRPBF?
The LTC6930CMS8-8.19#TRPBF has a typical long-term frequency stability of 30ppm/√kHr, measured at 30°C under continuous operation. Over five years (43.83kHr), this equates to √43.83 × 30ppm ≈ 198ppm (0.0198%) drift. Drift during unpowered storage is estimated at ~1/10th of powered drift, or ~3ppm/√kHr.
