Product details
Overview
LTC6930HDCB-8.19#TRMPBF from Analog Devices (acquired Linear Technology) is a digitally controlled silicon oscillator with factory-set 8.192MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 64kHz to 8.192MHz. It delivers ±0.1% max frequency accuracy over –40°C to 125°C, 105–500µA supply current (V+ = 3V), and <0.15% typical RMS period jitter - ideal for industrial microcontroller clocking where wide temperature operation and low power are critical.
For engineers reviewing the LTC6930HDCB-8.19#TRMPBF datasheet, LTC6930HDCB-8.19#TRMPBF pinout, LTC6930HDCB-8.19#TRMPBF application, or LTC6930HDCB-8.19#TRMPBF equivalent, this page provides verified pin functions, DCB package layout guidance, frequency selection logic, long-term drift data (30ppm/√kHr), and validated alternatives for high-reliability embedded timing.
Technical Context
The LTC6930HDCB-8.19#TRMPBF uses a proprietary switched-capacitor feedback loop to stabilize its internal 8.192MHz master oscillator across voltage (1.7V–5.5V) and temperature (–40°C to 125°C). Its three CMOS digital inputs (DIVA/DIVB/DIVC) configure binary dividers (1–128) to generate precise output frequencies without external components.
It features dual V+/GND pairs and an exposed thermal pad (Pin 9) to isolate the oscillator core from output driver noise. The 40Ω CMOS output driver supports ≤50pF capacitive or 1kΩ resistive loads with 3ns rise/fall time, and holds OUT low during startup to prevent glitches - enabling clean power-up in battery-operated systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT1533AI-H4-33E-32.768E | 32.768kHz fixed-output MEMS oscillator; ±10ppm initial accuracy; no digital frequency selection | Only supports single frequency; lacks DIV pin flexibility and wide-range output capability | Choose only if 32.768kHz is sufficient and ultra-low power (<1µA) is prioritized over configurability |
| MAX7375EKA+T | 32.768kHz to 1MHz programmable oscillator; ±500ppm accuracy over –40°C to 85°C; higher jitter (1.5% RMS) | Lower accuracy and narrower temperature range; not qualified for 125°C industrial use | Select when cost sensitivity outweighs precision and extended temperature requirements |

FAQ
What is the maximum operating temperature rating for the LTC6930HDCB-8.19#TRMPBF?
The LTC6930HDCB-8.19#TRMPBF is rated for continuous operation from –40°C to +125°C, with guaranteed ±0.1% frequency accuracy across this full range at V+ = 3V. This H-grade qualification makes it suitable for under-hood automotive, industrial control, and outdoor infrastructure applications where ambient temperatures exceed standard commercial or industrial grade limits.
How does the LTC6930HDCB-8.19#TRMPBF achieve its 8.192MHz nominal frequency?
The LTC6930HDCB-8.19#TRMPBF uses a factory-laser-trimmed master oscillator running at exactly 8.192MHz. Its internal binary divider (1–128) - controlled by the DIVA/DIVB/DIVC pins - generates eight precise output frequencies (e.g., 8.192MHz, 4.096MHz, 2.048MHz down to 64kHz) without external components. No user trimming or calibration is required.
Can the LTC6930HDCB-8.19#TRMPBF drive a 50pF capacitive load reliably?
Yes - the LTC6930HDCB-8.19#TRMPBF's 40Ω CMOS output driver is specified to drive up to 50pF capacitive load or 1kΩ resistive load. At 8.192MHz and 50pF, supply current increases to ~2.2mA (calculated as CLOAD × VSWING × fOSC), so ensure local 0.1µF bypass capacitors on both V+ pins (1 and 8) to handle transient current spikes.
Is the exposed thermal pad (Pin 9) of the LTC6930HDCB-8.19#TRMPBF electrically connected?
Yes - the exposed pad (Pin 9) on the LTC6930HDCB-8.19#TRMPBF is internally connected to GND and must be soldered to a PCB ground plane. This connection is mandatory for thermal dissipation, electrical noise reduction, and meeting specified jitter and accuracy performance. Failure to solder the pad degrades thermal resistance (θJA = 64°C/W) and may cause parametric shift.
What is the long-term frequency stability specification for the LTC6930HDCB-8.19#TRMPBF?
The LTC6930HDCB-8.19#TRMPBF has a typical long-term frequency stability of 30ppm/√kHr, measured at 30°C under nominal operating conditions. Over five years (43.83kHr), this equates to ~0.0198% total drift (≈198ppm), assuming continuous operation. Drift without power applied is estimated at ~3ppm/√kHr - significantly lower than powered operation.
