Product details
Overview
LTC6930HMS8-8.00#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set 8.000000MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 62.5kHz to 8.000MHz. It delivers ±0.1% frequency accuracy over –40°C to 125°C, 105–490µA supply current (V+ = 3V), and <0.15% RMS period jitter - enabling precision timing in harsh-temperature industrial control and automotive subsystems.
For engineers reviewing the LTC6930HMS8-8.00#TRPBF datasheet, LTC6930HMS8-8.00#TRPBF pinout, LTC6930HMS8-8.00#TRPBF application, or LTC6930HMS8-8.00#TRPBF equivalent, key selection criteria include its H-grade extended temperature operation, MSOP-8 package compatibility, low-power startup (<110µs), and digital frequency division without external components.
Technical Context
The LTC6930HMS8-8.00#TRPBF integrates a proprietary switched-capacitor-controlled master oscillator (factory-trimmed to 8.000000MHz) and a binary divider chain (÷1 to ÷128) driven by three CMOS logic inputs (DIVA/DIVB/DIVC). Its internal voltage regulation minimizes supply-induced frequency drift (0.07%/V), while dual V+/GND pin pairs isolate the output driver from control circuitry to suppress deterministic jitter.
Operation requires only 0.1µF bypass capacitors per V+/GND pair. The output is a rail-to-rail CMOS signal with 40Ω series resistance, 3ns rise/fall time, and 35–65% duty cycle - specified for 5pF load and ∞ resistive load, supporting direct interfacing with microcontrollers and logic ICs without external buffering.

FAQ
What is the maximum output frequency of the LTC6930HMS8-8.00#TRPBF?
The LTC6930HMS8-8.00#TRPBF has a factory-set master oscillator frequency of 8.000000MHz. When DIVA=DIVB=DIVC=0 (÷1 setting), the output frequency is exactly 8.000MHz - its maximum rated output. This value is confirmed in the "Frequency Setting and Available Frequencies" table and applies across the full –40°C to +125°C operating range for the H-grade device.
Does the LTC6930HMS8-8.00#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HMS8-8.00#TRPBF is a fully integrated silicon oscillator and requires no external load capacitors or crystals. Only 0.1µF ceramic bypass capacitors on each V+/GND pair are needed. This eliminates layout sensitivity, aging effects, and mechanical shock vulnerability inherent in crystal-based solutions - a key design advantage confirmed in the "Description" and "Applications Information" sections of the datasheet.
What is the guaranteed frequency accuracy of the LTC6930HMS8-8.00#TRPBF over temperature?
The LTC6930HMS8-8.00#TRPBF is guaranteed to maintain ±0.1% frequency accuracy over its full operating temperature range of –40°C to +125°C. This specification is explicitly stated under "Frequency Accuracy (Note 4)" for the LTC6930H grade in the AC Electrical Characteristics table and applies across the entire supply voltage range (1.7V–5.5V) and all DIV settings.
Can the DIV pins of the LTC6930HMS8-8.00#TRPBF be changed dynamically during operation?
Yes, the DIVA/DIVB/DIVC pins of the LTC6930HMS8-8.00#TRPBF can be reconfigured dynamically during operation. The datasheet confirms clean switching "within a single clock cycle without introducing any sliver or runt pulses." This behavior is validated in the "Switching the DIV Pins" section and supported by the CMOS input thresholds (VIH ≥ 1.25V, VIL ≤ 1.25V), enabling real-time frequency adaptation in firmware-controlled systems.
What package type and lead finish does the LTC6930HMS8-8.00#TRPBF use?
The LTC6930HMS8-8.00#TRPBF uses an 8-lead plastic MSOP (MS8) package measuring 3.00mm × 3.00mm, with lead-free (Pb-free) finish and tape-and-reel packaging (#TRPBF suffix). This is confirmed in the "Order Information" table on page 3 of the datasheet, where "LTC6930HMS8-8.00#TRPBF" is explicitly listed with "8-Lead Plastic MSOP" and "–40°C to 125°C" temperature range.
