3-Pin Silicon Oscillator
General Description
Features
♦ 2.7V to 5.5V Operation
♦ Factory-Trimmed Oscillator (600kHz to 9.99MHz)
♦ No External Components Required
♦ ±±0mꢀ Output ꢁriꢂe Current
The MAX7375 is a silicon oscillator, intended as a low-
cost improvement replacing ceramic resonators, crys-
tals, and crystal oscillator modules used as the clock
source for microcontrollers and UARTs in 3V, 3.3V, and
5V applications.
♦ 2% Initial ꢀccuracy
♦ ±50ppmꢃ/C Temp ꢁriꢄt
♦ Fast Startup Time: 5µs
♦ 40% to 60% Maximum ꢁuty Cycle
♦ 5ns Output Rise and Fall Time-Low EMI
The MAX7375 is a fully integrated oscillator, supplied at
specific factory-trimmed frequencies with a rail-to-rail
50% duty cycle square-wave output. The oscillator fre-
quency is generated directly without the use of a
phase-locked loop (PLL). No additional components
are used to set or adjust the frequency.
♦ Very Low EMI Susceptibility-No High-Impedance
Unlike typical crystal and ceramic resonator oscillator
circuits, the MAX7375 is highly resistant to vibration
and EMI. The high output drive current and absence of
high-impedance nodes also makes the oscillator less
susceptible to dirty or humid operating conditions. With
a wide operating temperature range, the oscillator is a
good choice for demanding home appliance and auto-
motive environments.
Nodes
♦ Very Low Jitter: ±60psP-P at 8MHz
♦ Tiny Surꢄace-Mount Package (SC70)
♦ -40/C to +±25/C Temperature Range
Ordering Information
Available in 3-pin space-saving SC70 package, the
MAX7375 is offered in standard and nonstandard fac-
tory-set frequencies ranging from 600kHz to 9.99MHz.
See the MAX7381 data sheet for frequencies ≥10MHz.
The MAX7375’s standard operating temperature range
is -40°C to +125°C. See the Applications Information
section for extended operating temperature range.

Note: The MAX7375 is available in factory-set frequencies from
600kHz to 9.99MHz. There are seven standard versions (1MHz,
1.84MHz, 3.58MHz, 3.69MHz, 4MHz, 4.19MHz, and 8MHz, as
shown in the Selector Guide) with a required 2.5k order incre-
ment. Nonstandard frequencies are also available with a required
10k order increment. For nonstandard versions, contact factory
for availability and ordering information. All versions available in
tape-and-reel only.
