Product details
Overview
LTC6930HDCB-7.37#TRMPBF 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 to output frequencies from 57.6kHz to 7.3728MHz. It delivers ±0.1% frequency accuracy over –40°C to 125°C, consumes only 183µA typical at 3V/7.37MHz, and features <110µs start-up time. It serves as a precision timing source in high-reliability industrial control and automotive subsystems.
For engineers reviewing the LTC6930HDCB-7.37#TRMPBF datasheet, LTC6930HDCB-7.37#TRMPBF pinout, LTC6930HDCB-7.37#TRMPBF application, or LTC6930HDCB-7.37#TRMPBF equivalent, key selection criteria include its H-grade temperature range (–40°C to 125°C), DFN-8 (2mm × 3mm) package with exposed thermal pad, 0.09% max initial frequency error at 25°C, RMS period jitter <0.97ns at 7.3728MHz, and supply current scalability across 1.7V–5.5V operation.
Technical Context
The LTC6930HDCB-7.37#TRMPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 7.3728MHz master oscillator against temperature and supply variation. Its digital divider architecture uses three CMOS input pins (DIVA/DIVB/DIVC) to select one of eight binary division ratios (1 to 128), enabling precise frequency synthesis without external components.
It integrates dual V+ and GND pins (Pins 1/8 and 2/6) to isolate the oscillator core from output switching noise, and employs a low-impedance 40Ω CMOS output driver with 3ns rise/fall time to drive up to 50pF capacitive loads while minimizing deterministic jitter and supply rail disturbance.

Pinout & Package
Package: 8-lead (2mm × 3mm) plastic DFN (DCB) with exposed thermal pad (Pin 9), RoHS-compliant, lead-free finish. Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| OUT (Pin 7) | CMOS clock output | Low-impedance (40Ω typ) push-pull driver; holds low during start-up; glitch-free on DIV pin changes |
| Exposed Pad (Pin 9) | Thermal & electrical ground | Mandatory solder connection to PCB ground plane; improves thermal dissipation and reduces ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Digital frequency selection | Three-pin binary interface selects exact output frequency from 8 options - eliminates need for external crystals or trimming components |
| Ultralow power operation | 183µA typical at 7.37MHz/3V - enables continuous timing in energy-constrained edge devices |
| H-grade temperature range | –40°C to 125°C operation - qualified for under-hood automotive and industrial motor control environments |

FAQ
What is the maximum operating temperature for the LTC6930HDCB-7.37#TRMPBF?
The LTC6930HDCB-7.37#TRMPBF is rated for continuous operation from –40°C to 125°C, meeting the H-grade specification. This makes it suitable for under-hood automotive applications and industrial equipment exposed to elevated ambient temperatures. The device's frequency accuracy remains within ±1.0% across this full range, and thermal derating is not required up to 125°C junction temperature.
How do I configure the LTC6930HDCB-7.37#TRMPBF to output 1.8432MHz?
To output 1.8432MHz, set DIVA = 0, DIVB = 1, DIVC = 0 (binary 010) on the LTC6930HDCB-7.37#TRMPBF. This selects ÷4 division of the factory-programmed 7.3728MHz master oscillator. Connect DIVB to V+ and DIVA/DIVC to GND. No external resistors or pull-ups are needed - the inputs accept standard CMOS logic levels.
Does the LTC6930HDCB-7.37#TRMPBF require external load capacitors like quartz crystals?
No, the LTC6930HDCB-7.37#TRMPBF does not require external load capacitors. It is a fully integrated silicon oscillator with internal frequency generation and regulation. Only two 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are required for stable operation. This eliminates crystal matching, PCB layout sensitivity, and aging-related drift inherent in quartz solutions.
What is the typical supply current of the LTC6930HDCB-7.37#TRMPBF at 3.3V and 7.3728MHz?
At 3.3V supply and 7.3728MHz output (DIV = 1), the LTC6930HDCB-7.37#TRMPBF draws 183µA typical supply current, as specified in the DC Electrical Characteristics table. This value scales linearly with load capacitance and supply voltage - for example, driving 50pF instead of the test 5pF increases current by ~2.2mA due to capacitive charging, but the base oscillator core current remains unchanged.
Can the LTC6930HDCB-7.37#TRMPBF be used as a direct replacement for a 7.3728MHz crystal oscillator module?
Yes, the LTC6930HDCB-7.37#TRMPBF can replace a 7.3728MHz crystal oscillator module in most cases. It provides identical frequency, CMOS-compatible output, and operates from the same 1.7V–5.5V supply. However, unlike modules, it offers digital frequency selection (down to 57.6kHz) and consumes significantly less power (183µA vs typically 1–5mA). Layout changes are minimal - only two 0.1µF bypass caps are needed instead of crystal load caps.
