Fixed 7.3728 MHz clock source — no PLL, no crystal
The LTC6930IDCB-7.37#TRMPBF is a silicon oscillator from Analog Devices delivering a fixed 7.3728 MHz output — a frequency that divides cleanly to common baud rates (115200, 57600) and MCU clock multiples, eliminating the need for an external crystal or PLL multiplier. Supply current is 853 µA typical at 7.3728 MHz, making it a low-power alternative to crystal oscillators in battery-operated or thermally constrained designs.
Operating from 1.7V to 5.5V, the oscillator runs directly off a single Li-ion cell, a 3.3V rail, or a 5V supply without an intermediate LDO — simplifies the power tree and saves a regulator slot on the BOM.
Package and layout — 8-DFN with exposed pad
ROHS3 compliant.
