Analog Devices Inc. LTC6930MPMS8-5.00#TRPBF

Overview

LTC6930MPMS8-5.00#TRPBF from Analog Devices (formerly Linear Technology) is a precision micropower silicon oscillator with factory-set 5.000000MHz master frequency, digitally programmable via three DIV pins to output eight discrete frequencies from 39.0625kHz to 5.000MHz. It delivers ±0.1% frequency accuracy over –55°C to 125°C, consumes only 124µA typical at 3V/5MHz, and features <110µs power-on delay - ideal for high-reliability industrial timing in harsh environments.

For engineers reviewing the LTC6930MPMS8-5.00#TRPBF datasheet, LTC6930MPMS8-5.00#TRPBF pinout, LTC6930MPMS8-5.00#TRPBF application, or LTC6930MPMS8-5.00#TRPBF equivalent, this page provides verified package mapping (MS8), validated DIV pin logic table, confirmed RMS period jitter (0.97ps at 5MHz), supply current vs. divider setting data, and real-world long-term drift (30ppm/√kHr).

Technical Context

The LTC6930MPMS8-5.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator across temperature and supply voltage. Its digital control architecture uses three CMOS input pins (DIVA/DIVB/DIVC) to select binary division ratios (1–128), enabling eight precise output frequencies without external components.

It integrates dual V+ supply pins (Pins 1 & 8) and dual GND pins (Pins 2 & 6) to isolate the oscillator core from output switching noise. The 40Ω CMOS output driver supports ≤50pF capacitive load with 3ns rise/fall time and maintains 48–52% duty cycle across all dividers and 1.7–5.5V supply range.

FAQ

What is the guaranteed frequency accuracy of the LTC6930MPMS8-5.00#TRPBF over its full operating temperature range?

The LTC6930MPMS8-5.00#TRPBF guarantees ±0.1% frequency accuracy over its full –55°C to 125°C operating range. This specification applies to all eight output frequencies derived from the 5.000000MHz master oscillator via the DIV pins, and is measured at V+ = 3V with C_LOAD = 5pF. The MP grade achieves this tighter tolerance through enhanced process screening and characterization.

Can the LTC6930MPMS8-5.00#TRPBF generate frequencies outside the eight values listed in Table 1?

No - the LTC6930MPMS8-5.00#TRPBF outputs only the eight discrete frequencies defined by its 5.000000MHz master oscillator divided by integer factors 1, 2, 4, 8, 16, 32, 64, or 128. These yield 5.000MHz, 2.500MHz, 1.250MHz, 625.0kHz, 312.5kHz, 156.25kHz, 78.125kHz, and 39.0625kHz. Custom frequencies require factory programming of a different master oscillator (e.g., LTC6930MPMS8-8.19#TRPBF).

How does the LTC6930MPMS8-5.00#TRPBF achieve low jitter despite being a silicon oscillator?

The LTC6930MPMS8-5.00#TRPBF achieves 0.97ps RMS period jitter at 5MHz through a proprietary switched-capacitor feedback loop that actively stabilizes its master oscillator against thermal and supply noise. Dual V+ and GND pins isolate the oscillator core from output switching transients, while the 40Ω CMOS driver with controlled 3ns edge rates minimizes deterministic jitter contributions from load-dependent slew effects.

Is the MS8 package of the LTC6930MPMS8-5.00#TRPBF lead-free and RoHS compliant?

Yes - the LTC6930MPMS8-5.00#TRPBF carries the "#TRPBF" suffix, indicating lead-free (Pb-free) finish and full compliance with EU RoHS Directive 2011/65/EU and JEDEC JS-001 ESD standards. The MS8 package uses matte tin plating over copper leadframe and meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30°C/85% RH.

What is the recommended bypass capacitor configuration for the LTC6930MPMS8-5.00#TRPBF?

Each V+ pin (Pins 1 and 8) must be bypassed directly to its adjacent GND pin (Pin 2 for V+1, Pin 6 for V+8) using a 0.1µF X7R ceramic capacitor placed ≤2mm from the device. These capacitors decouple high-frequency supply spikes generated by the 40Ω output driver, especially under heavy capacitive loading. A shared bulk capacitor (e.g., 1–10µF tantalum) may be added elsewhere on the rail but does not replace the local 0.1µF placements.
