ABM8-16.000MHZ-B2-T

Abracon · Quartz crystal resonator · ABM8 SMD 3.2x2.5mm (4-pad)

16.000 MHz fundamental-mode quartz crystal resonator in a 3.2 x 2.5 mm 4-pad seam-sealed ceramic SMD package, from Abracon's ABM8 series. Load capacitance is 18 pF, frequency tolerance ±20 ppm, and ESR is 70 ohm max. Two active crystal terminals plus two case-ground pads that tie the metal lid to ground. The clock source for MCUs and USB devices; pair with two ~18 pF load capacitors to ground.

Pinout

Pin Name Type Function
1 XTAL1 passive Crystal terminal 1. Connect to the oscillator input of the driving circuit through a load capacitor sized for CL = 18 pF. Fundamental-mode 16.000 MHz resonator terminal.
2 GND passive Case ground pad. Tied to the metal lid of the seam-sealed package for shielding; connect to the board ground plane.
3 XTAL2 passive Crystal terminal 2. Connect to the oscillator output of the driving circuit through a load capacitor sized for CL = 18 pF. Fundamental-mode 16.000 MHz resonator terminal.
4 GND passive Case ground pad. Tied to the metal lid of the seam-sealed package for shielding; connect to the board ground plane.
