Analog Devices Inc. LTC6930MPMS8-4.19#TRPBF

Overview

LTC6930MPMS8-4.19#TRPBF from Analog Devices (formerly Linear Technology) is a precision micropower silicon oscillator with factory-set master frequency of 4.194304 MHz, digitally programmable via DIVA/DIVB/DIVC pins to output any of eight frequencies from 32.768 kHz to 4.194304 MHz. It delivers ±0.1% frequency accuracy over –55°C to 125°C, 105 µA typical supply current at 32 kHz/3 V, and <110 µs start-up time - ideal for low-power industrial sensor nodes and extended-life battery systems.

For engineers reviewing the LTC6930MPMS8-4.19#TRPBF datasheet, LTC6930MPMS8-4.19#TRPBF pinout, LTC6930MPMS8-4.19#TRPBF application, or LTC6930MPMS8-4.19#TRPBF equivalent, key selection criteria include its guaranteed –55°C to 125°C operation, MS8 package compatibility, 0.09% max initial error at 25°C, RMS period jitter <0.15% at 3 V, and no external components required beyond 0.1 µF bypass capacitors.

Technical Context

The LTC6930MPMS8-4.19#TRPBF integrates a proprietary switched-capacitor-controlled master oscillator (4.194304 MHz) and a binary divider chain (÷1 to ÷128) controlled by three CMOS digital inputs (DIVA/DIVB/DIVC). Its internal regulation ensures <0.07%/V supply-induced frequency drift and 0.0001%/°C temperature drift in the MS8 package.

It uses dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate power delivery from the 40 Ω CMOS output driver (Pin 7), enabling clean 50 pF–capacitive or 1 kΩ–resistive loading without runt pulses during DIV pin transitions or power-up.

FAQ

What is the guaranteed operating temperature range for the LTC6930MPMS8-4.19#TRPBF?

The LTC6930MPMS8-4.19#TRPBF is specified for continuous operation from –55°C to 125°C. This extended range is validated per the MP-grade qualification standard and applies across all electrical parameters including frequency accuracy, supply current, and start-up time - making it suitable for aerospace, downhole, and under-hood automotive use cases where commercial or industrial grades fall short.

How does the LTC6930MPMS8-4.19#TRPBF achieve its 0.09% initial frequency accuracy without external calibration?

The LTC6930MPMS8-4.19#TRPBF achieves ±0.09% initial accuracy at 25°C through factory laser-trimming of its proprietary switched-capacitor feedback loop during final test. This monolithic silicon oscillator architecture eliminates quartz crystal variability and avoids post-assembly calibration steps - delivering known accuracy immediately upon power-up.

Can the LTC6930MPMS8-4.19#TRPBF drive a 50 pF capacitive load reliably?

Yes, the LTC6930MPMS8-4.19#TRPBF output driver is rated for up to 50 pF capacitive loading. Its 40 Ω series resistance and 3 ns rise/fall time limit RF emissions while maintaining signal integrity. At 4.194 MHz and 3 V supply, driving 50 pF increases supply current by ~2.2 mA (calculated via C·V·f), which must be accommodated by local 0.1 µF bypass capacitors on both V+ pins.

What happens to the OUT pin during power-up and DIV pin changes?

During power-up, the OUT pin is held low for <110 µs until the oscillator stabilizes - preventing glitches or invalid clock edges to downstream logic. When DIV pins change state, the output transitions cleanly within one full clock cycle with no runt pulses, slivers, or metastability - enabling safe dynamic frequency reconfiguration in real-time systems using the LTC6930MPMS8-4.19#TRPBF.

Is the LTC6930MPMS8-4.19#TRPBF pin-compatible with other LTC6930 variants in the MS8 package?

Yes, all LTC6930 variants in the MS8 package - including LTC6930CMS8-4.19#TRPBF, LTC6930IMS8-4.19#TRPBF, and LTC6930HMS8-4.19#TRPBF - share identical pinout, footprint, and electrical interface. The only differences are temperature grade qualification and associated parametric limits; the LTC6930MPMS8-4.19#TRPBF provides the widest operational range.
