Product details
Overview
LTC6930CDCB-5.00#TRMPBF from Analog Devices (formerly Linear Technology) is a digitally controlled silicon oscillator with factory-set 5.000000MHz master frequency, selectable via DIVA/DIVB/DIVC pins across eight output frequencies (39.0625kHz to 5.000MHz), ±0.1% frequency accuracy over 0°C to 70°C, <110µs start-up time, and 124µA typical supply current at 3V. It serves as a precision clock source in battery-powered microcontroller systems.
For engineers reviewing the LTC6930CDCB-5.00#TRMPBF datasheet, LTC6930CDCB-5.00#TRMPBF pinout, LTC6930CDCB-5.00#TRMPBF application, or LTC6930CDCB-5.00#TRMPBF equivalent, key selection criteria include its 0.09% max initial frequency error at 25°C, DFN-8 (2mm × 3mm) package with exposed thermal pad, RMS period jitter <0.8ns at 5MHz, and support for 1.7V–5.5V single-supply operation without external timing components.
Technical Context
The LTC6930CDCB-5.00#TRMPBF implements a proprietary switched-capacitor feedback loop to stabilize its internal 5.000000MHz master oscillator across temperature and supply voltage variations. Its digital control architecture uses three CMOS input pins (DIVA/DIVB/DIVC) to select binary division ratios from 1 to 128, enabling deterministic frequency synthesis without crystal load dependency.
It features dual V+ and GND pins adjacent to the OUT pin to isolate the output driver's high-frequency switching from the control loop, achieving <0.8ns RMS period jitter at 5MHz while maintaining <0.1% frequency drift over 0°C to 70°C. The device holds the OUT pin low during power-up until stable oscillation is confirmed, eliminating runt pulses during DIV pin transitions.
Key Specifications

FAQ
What is the maximum output frequency achievable with LTC6930CDCB-5.00#TRMPBF?
The LTC6930CDCB-5.00#TRMPBF has a factory-set 5.000000MHz master oscillator. Its maximum output frequency is 5.000MHz, achieved when DIVA=DIVB=DIVC=0 (division ratio = 1). All other DIV settings produce lower frequencies per Table 1 in the datasheet, down to 39.0625kHz.
Does LTC6930CDCB-5.00#TRMPBF require external load capacitors like quartz crystals?
No, the LTC6930CDCB-5.00#TRMPBF is a fully integrated silicon oscillator and requires no external load capacitors. Only standard 0.1µF ceramic bypass capacitors between each V+ pin and its adjacent GND pin are needed for stable operation.
How does the exposed thermal pad (Pin 9) on LTC6930CDCB-5.00#TRMPBF affect performance?
The exposed pad on LTC6930CDCB-5.00#TRMPBF must be soldered to a PCB ground plane. This connection reduces thermal resistance (θJA = 64°C/W), stabilizes ground reference for the output driver, and lowers RMS period jitter by minimizing substrate noise coupling into the oscillator core.
Can LTC6930CDCB-5.00#TRMPBF operate from a 1.8V supply?
Yes, LTC6930CDCB-5.00#TRMPBF supports supply voltages from 1.7V to 5.5V. At 1.8V, typical supply current is 95µA (DIV=1, 5MHz), and frequency accuracy remains within ±0.8% over full temperature range per AC Electrical Characteristics table.
What is the function of the DIVA, DIVB, and DIVC pins on LTC6930CDCB-5.00#TRMPBF?
The DIVA, DIVB, and DIVC pins on LTC6930CDCB-5.00#TRMPBF are CMOS logic inputs that configure the internal binary divider. Their 3-bit state selects division ratios from 1 to 128 (e.g., [000] = ÷1 = 5.000MHz; [001] = ÷2 = 2.500MHz), enabling eight discrete output frequencies without external components.
