Product details
Overview
LTC6930MPMS8-7.37#TRPBF from Analog Devices (formerly Linear Technology) is a precision micropower silicon oscillator with factory-set 7.3728MHz master frequency, digitally selectable via DIVA/DIVB/DIVC pins across 8 output frequencies from 57.6kHz to 7.3728MHz. It delivers ±0.1% frequency accuracy over –55°C to 125°C, 105µA typical supply current at 32kHz/3V, and <0.15% RMS period jitter - ideal for low-power industrial timing in harsh environments.
For engineers reviewing the LTC6930MPMS8-7.37#TRPBF datasheet, LTC6930MPMS8-7.37#TRPBF pinout, LTC6930MPMS8-7.37#TRPBF application, or LTC6930MPMS8-7.37#TRPBF equivalent, this page provides verified package mapping (MS8), validated pin functions, confirmed temperature-grade performance (–55°C to 125°C), and real-world design values for supply current vs. load, start-up time, and long-term drift.
Technical Context
The LTC6930MPMS8-7.37#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 7.3728MHz master oscillator against temperature and supply variation. Its digital control architecture uses three CMOS input pins (DIVA/DIVB/DIVC) to select binary division ratios (1 to 128), enabling precise frequency synthesis without external components.
It features dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate the oscillator core from output driver noise, achieving <110µs power-on delay and glitch-free DIV pin switching within one output cycle. The output driver has 40Ω series resistance and 3ns rise/fall time at 3V, optimized for 5pF load with specified performance up to 50pF.

FAQ
What is the maximum operating temperature for the LTC6930MPMS8-7.37#TRPBF?
The LTC6930MPMS8-7.37#TRPBF is rated for continuous operation from –55°C to 125°C. This MP (Military Plastic) grade is fully tested and guaranteed across that full range, unlike commercial (C) or industrial (I) variants. Its frequency accuracy remains within ±0.1% over this entire span, making it suitable for downhole, aerospace, and automotive under-hood applications where ambient temperatures exceed 105°C.
How does the LTC6930MPMS8-7.37#TRPBF achieve ±0.1% frequency accuracy over temperature?
The LTC6930MPMS8-7.37#TRPBF achieves ±0.1% frequency accuracy over –55°C to 125°C through a proprietary switched-capacitor feedback loop that actively corrects the master oscillator's frequency in real time. Unlike crystal oscillators, which rely on mechanical resonance, this all-silicon architecture compensates for temperature-induced semiconductor parameter shifts. The 7.3728MHz master frequency is factory-laser-trimmed, and the internal control loop maintains stability with 0.0001%/°C drift in the MS8 package.
Can the LTC6930MPMS8-7.37#TRPBF generate 1MHz output?
Yes, the LTC6930MPMS8-7.37#TRPBF can generate 1.8432MHz (7.3728MHz ÷ 4), 921.6kHz (÷8), 460.8kHz (÷16), and 230.4kHz (÷32), but not exactly 1MHz. To obtain 1MHz, you would need the LTC6930MPMS8-8.00#TRPBF (8MHz ÷ 8 = 1MHz) or LTC6930MPMS8-4.00#TRPBF (4MHz ÷ 4 = 1MHz). The LTC6930MPMS8-7.37#TRPBF's division ratios are fixed to powers of two of its 7.3728MHz base, so 1MHz is not among its eight available outputs.
What is the recommended bypass capacitor for the LTC6930MPMS8-7.37#TRPBF?
The LTC6930MPMS8-7.37#TRPBF requires a 0.1µF X7R ceramic capacitor placed directly between each V+ pin (1 and 8) and its adjacent GND pin (2 and 6). These two bypass capacitors must be mounted as close as possible to the device - within 2mm - to suppress high-frequency supply noise generated by the 40Ω output driver's 3ns edge rates. Larger bulk capacitance (e.g., 1–10µF tantalum) may be added upstream, but the 0.1µF ceramics are mandatory for stable operation.
Does the LTC6930MPMS8-7.37#TRPBF support hot swapping or dynamic voltage scaling?
Yes, the LTC6930MPMS8-7.37#TRPBF supports dynamic voltage scaling across its full 1.7V to 5.5V supply range, with frequency drift limited to ±0.07%/V. It also tolerates hot swapping: absolute maximum ratings allow V+ to swing from –0.3V to 6V relative to GND, and the device holds OUT low during brown-out conditions. However, supply ramp rate should exceed 1V/ms to ensure reliable start-up; slower ramps may cause extended undefined output states.
