Analog Devices Inc. LTC6930HMS8-7.37#TRPBF

Overview

LTC6930HMS8-7.37#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set 7.3728MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 57.6kHz to 7.3728MHz. It delivers ±0.1% frequency accuracy over –40°C to 125°C, 105–453µA supply current at 3V, and <0.15% RMS period jitter - ideal for industrial microcontroller clocking where wide temperature stability and ultra-low power are critical.

For engineers reviewing the LTC6930HMS8-7.37#TRPBF datasheet, LTC6930HMS8-7.37#TRPBF pinout, LTC6930HMS8-7.37#TRPBF application, or LTC6930HMS8-7.37#TRPBF equivalent, key selection criteria include its H-grade extended temperature operation, MSOP-8 package compatibility, digital frequency selection without external components, and verified performance under 1.7V–5.5V single-supply conditions.

Technical Context

The LTC6930HMS8-7.37#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 7.3728MHz master oscillator across voltage and temperature extremes. Its three CMOS digital inputs (DIVA/DIVB/DIVC) configure binary division ratios (1–128), enabling precise output frequencies without trimming or external circuitry.

It features dual V+ pins (1 and 8) and dual GND pins (2 and 6) to isolate oscillator core and output driver sections, minimizing deterministic jitter. The output stage uses a low-impedance (40Ω typical at 3V) CMOS driver with 3ns rise/fall time, optimized for driving 5pF loads while maintaining <0.15% RMS jitter and 35–65% duty cycle across supply and divide settings.

FAQ

What is the maximum operating temperature specification for the LTC6930HMS8-7.37#TRPBF?

The LTC6930HMS8-7.37#TRPBF is rated for continuous operation from –40°C to +125°C ambient temperature, with full electrical specifications guaranteed across this range. This H-grade qualification distinguishes it from C- and I-grade variants and makes it suitable for under-hood automotive and industrial control applications where junction temperatures may exceed 100°C.

How does the LTC6930HMS8-7.37#TRPBF achieve ±0.1% frequency accuracy without external components?

The LTC6930HMS8-7.37#TRPBF achieves ±0.1% accuracy through a factory-trimmed, proprietary switched-capacitor feedback loop that stabilizes its internal 7.3728MHz master oscillator against voltage, temperature, and process variations. No external crystal, capacitors, or resistors are needed - all compensation is implemented on-die using precision analog circuitry and digital calibration data stored during manufacturing.

Can the LTC6930HMS8-7.37#TRPBF output frequency be changed dynamically during operation?

Yes, the LTC6930HMS8-7.37#TRPBF supports real-time frequency changes via its DIVA, DIVB, and DIVC pins. Switching these inputs causes the output to transition cleanly to the new frequency within one clock cycle, with no glitches, runt pulses, or undefined states - enabling adaptive clocking for power-managed subsystems.

What is the recommended power supply decoupling for the LTC6930HMS8-7.37#TRPBF?

Each V+ pin (1 and 8) must be bypassed directly to its adjacent GND pin (2 and 6, respectively) with a 0.1µF X7R ceramic capacitor placed as close as possible to the device. This dual-decoupling scheme isolates the oscillator core and output driver supply domains, minimizing crosstalk and preserving jitter performance - especially critical when driving capacitive loads >10pF.

Does the LTC6930HMS8-7.37#TRPBF require a specific load capacitance to meet its specified jitter and accuracy?

No - the LTC6930HMS8-7.37#TRPBF's jitter (0.97nsP-P) and accuracy (±0.1%) specifications are guaranteed with a 5pF capacitive load and infinite resistive load, per the datasheet test conditions. While it can drive up to 50pF, increased load capacitance raises supply current linearly and may marginally increase jitter; design margins should be verified at the target load.
