Microcontroller with 10-Bit ADC,
PGA, 64KB Flash, and CAN Interface
The MAXQ7670 uses an 8MHz or 16MHz Jauch
JXG53P2 (or similar specification):
Frequency: 8MHz or 16MHz ±0.25%.

Series resonance resistance: max 50Ω/300Ω for
16MHz/8MHz, respectively.
Note: Series resonance resistance is the resistance
observed when the resonator is in the series resonant
condition. This is a parameter often stated by quartz
crystal vendors and is called R1. When a resonator is
used in the parallel resonant mode with an external
load capacitance, as is the case with the MAXQ7670
oscillator circuit, the effective resistance is sometimes
stated. This effective resistance at the loaded frequen-
cy of oscillation is:
