CRYSTAL SPECIFICATION

The crystal oscillators should be fundamental mode quartz crystals:

overtone crystals are not suitable. Crystal frequency should be specified

for parallel resonance with 50

Ω maximum equivalent series resonance.

NOTE:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause

permanent damage to the device. This is a stress rating only and functional operation

of the device at these or any other conditions above those indicated in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

NOTES:

1. H = HIGH

M = MEDIUM

L = LOW

2. Test mode for low frequency testing. In this mode, REF clock bypasses the VCO (VCO powered down) and the crystal oscillator is powered down.
