Product details
Overview
LTC6930MPMS8-8.00#TRPBF from Analog Devices (formerly Linear Technology) is a precision micropower silicon oscillator with factory-set 8.000000MHz master frequency, digitally selectable via DIVA/DIVB/DIVC pins to output frequencies from 62.5kHz to 8.000MHz in binary division steps. It delivers ±0.1% frequency accuracy over –55°C to 125°C, <110µs start-up time, and 491µA typical supply current at 3V/8MHz - ideal for battery-powered industrial sensors and aerospace telemetry systems requiring stable timing under extreme thermal stress.
For engineers reviewing the LTC6930MPMS8-8.00#TRPBF datasheet, LTC6930MPMS8-8.00#TRPBF pinout, LTC6930MPMS8-8.00#TRPBF application, or LTC6930MPMS8-8.00#TRPBF equivalent, key selection criteria include its extended temperature grade (–55°C to 125°C), MSOP-8 package compatibility, low 0.15% RMS period jitter at 8MHz, and absence of external load capacitors - critical for space-constrained, high-reliability embedded timing designs.
Technical Context
The LTC6930MPMS8-8.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 8.000MHz master oscillator across voltage (1.7V–5.5V) and temperature extremes. Its three digital DIV inputs control an on-chip binary divider (1–128), enabling eight discrete output frequencies without external components.
It features dual V+ pins (1,8) and dual GND pins (2,6) to isolate oscillator core from output driver noise, and a 40Ω CMOS output stage with 3ns rise/fall time optimized for driving 5pF loads while minimizing RF emissions - essential for mixed-signal systems where clock integrity directly impacts ADC sampling or serial communication reliability.

FAQ
What is the guaranteed frequency accuracy of the LTC6930MPMS8-8.00#TRPBF over its full operating temperature range?
The LTC6930MPMS8-8.00#TRPBF guarantees ±0.1% frequency accuracy over its full –55°C to 125°C operating temperature range, as specified in the Absolute Maximum Ratings and AC Electrical Characteristics tables of the official datasheet. This applies to all eight selectable output frequencies derived from the 8.000MHz master oscillator using the DIVA/DIVB/DIVC pins.
Can the LTC6930MPMS8-8.00#TRPBF operate from a single 1.8V supply?
Yes, the LTC6930MPMS8-8.00#TRPBF supports supply voltages from 1.7V to 5.5V, making it fully operational at 1.8V. At this voltage and 8MHz output, the typical supply current is 520µA (per DC Electrical Characteristics table), and frequency accuracy remains within ±0.8% over the full temperature range.
Does the LTC6930MPMS8-8.00#TRPBF require external load capacitors on its OUT pin?
No, the LTC6930MPMS8-8.00#TRPBF requires no external load capacitors. Its CMOS output driver is designed to drive up to 50pF directly, and all specifications - including jitter and start-up time - are characterized with a 5pF load. Only 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are mandatory.
How does the LTC6930MPMS8-8.00#TRPBF achieve its fast 110µs start-up time?
The LTC6930MPMS8-8.00#TRPBF achieves sub-110µs start-up through a proprietary control architecture that pre-biases internal circuitry during power ramp-up. The output remains held low until the first valid clock edge is generated, eliminating runt pulses or frequency instability - a key advantage over crystal oscillators requiring milliseconds to stabilize.
Is the MSOP-8 package of the LTC6930MPMS8-8.00#TRPBF pin-compatible with the DFN-8 variant?
No, the MSOP-8 (LTC6930MPMS8-8.00#TRPBF) and DFN-8 (e.g., LTC6930MPDCB-8.00#TRPBF) packages have different pinouts and footprints. The MSOP uses pins 1–8 in standard MSOP order; the DFN adds an exposed thermal pad (Pin 9) and rearranges pin assignments. PCB layout must be redesigned when switching between these packages.
