Product details
Overview
LTC6930HDCB-5.00#TRPBF from Analog Devices (formerly Linear Technology) is a digitally controlled, precision silicon oscillator with factory-set 5.000000MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies from 39.0625kHz to 5.000MHz. It delivers ±0.1% frequency accuracy over –40°C to 125°C, consumes only 124µA typical at 3V/5MHz, and achieves <110µs power-on delay - ideal for high-reliability industrial timing in harsh-temperature environments.
For engineers reviewing the LTC6930HDCB-5.00#TRPBF datasheet, LTC6930HDCB-5.00#TRPBF pinout, LTC6930HDCB-5.00#TRPBF application, or LTC6930HDCB-5.00#TRPBF equivalent, this page provides verified specifications, package layout, temperature-stable jitter performance (<0.15% RMS period jitter), supply voltage flexibility (1.7V–5.5V), and direct replacement guidance for high-accuracy µPower clocking.
Technical Context
The LTC6930HDCB-5.00#TRPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator against temperature and supply variation. Its three digital DIV inputs control an on-chip binary divider (1–128), enabling precise frequency selection 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 integrates a low-impedance 40Ω CMOS output stage with 3ns rise/fall time - ensuring clean signal integrity into 5pF loads while minimizing RF interference in dense PCB layouts.

Pinout & Package
Package: 8-lead (2mm × 3mm) plastic DFN (DCB), exposed pad (Pin 9) required to be soldered to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-32.768D | 32.768kHz fixed-output MEMS oscillator; ±10ppm initial accuracy; no DIV pins; 1.62–3.63V supply | Only supports 32.768kHz; lacks programmable frequency selection and wide-range voltage operation | Select when only ultra-low-power RTC timing is needed and frequency flexibility is unnecessary |
| MAX7375ATB+T | 5.0MHz fixed-output silicon oscillator; ±50ppm over –40°C to +85°C; 1.7–5.5V supply; no DIV control | Lower accuracy grade; limited to commercial/industrial temp range; no frequency reconfiguration | Select for cost-sensitive applications where ±0.005% accuracy is sufficient and extended temperature operation is not required |

FAQ
What is the maximum operating temperature for the LTC6930HDCB-5.00#TRPBF?
The LTC6930HDCB-5.00#TRPBF is rated for continuous operation from –40°C to +125°C. This H-grade qualification is confirmed in the Absolute Maximum Ratings and Specified Temperature Range tables, and applies across all electrical parameters including frequency accuracy (±0.1%), supply current, and jitter performance. The DFN package's exposed pad must be soldered to GND to maintain thermal integrity at upper temperature limits.
How do I configure the LTC6930HDCB-5.00#TRPBF to output 2.5MHz?
To configure the LTC6930HDCB-5.00#TRPBF for 2.5MHz output, set DIVA = HIGH (V+), DIVB = LOW (GND), DIVC = LOW (GND), corresponding to binary [001] per Table 1. This selects ÷2 division of the factory-programmed 5.000000MHz master oscillator. No external components are needed - only proper V+/GND bypassing and correct logic levels on the three DIV pins.
Does the LTC6930HDCB-5.00#TRPBF require external load capacitors like quartz crystals?
No, the LTC6930HDCB-5.00#TRPBF does not require external load capacitors. It is a fully integrated silicon oscillator with internal resonator and regulation circuitry. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are required - as shown in Figure 1 of the datasheet. This eliminates crystal matching, PCB layout sensitivity, and aging-related frequency drift.
What is the typical supply current of the LTC6930HDCB-5.00#TRPBF at 3.3V and 5MHz output?
At V+ = 3V and 5.000MHz output (DIV = 1), the LTC6930HDCB-5.00#TRPBF draws 124µA typical supply current, with a maximum of 190µA over the full –40°C to +125°C range. At 3.3V, current scales linearly - approximately 128µA typical - as confirmed by the Supply Current vs Supply Voltage plot (Figure G06) and DC Electrical Characteristics table.
Can the LTC6930HDCB-5.00#TRPBF be used as a drop-in replacement for a 5MHz quartz crystal?
The LTC6930HDCB-5.00#TRPBF is not a drop-in replacement for a 5MHz quartz crystal because it is an active oscillator (3-pin device: V+, GND, OUT) versus a passive 2-pin resonator. It replaces the entire crystal + load cap + oscillator circuit, requiring only V+, GND, and OUT connections. PCB layout must accommodate the 8-lead DFN footprint and exposed pad - not the crystal's two-pad layout.
