5Mbps ARCNET (ANSI 878.1) Controller with 2K x 8 On-Chip RAM
or better. The oscillation frequency range is from 10 MHz to 20 MHz.
The crystal must have an accuracy of 0.010% or better when the internal clock multiplier is turned on. The oscillation
frequency must be 20MHz when the internal clock multiplier is turned on.
The XTAL2 side of the crystal may be loaded with a single 74HC-type buffer in order to generate a clock for other
devices.
The user may attach an external TTL clock, rather than a crystal, to the XTAL1 signal. In this case, a 390Ω pull-up
resistor is required on XTAL1, while XTAL2 should be left unconnected.
