XU Datasheet
Notes for all AC Electrical Characteristics tables:
1
A pull-up resistor from V
DD
to E/D enables output when pin 1 is left open.
2
Installation should include a 0.01μF bypass capacitor placed between VDD and GND to minimize power supply line noise.
3
Stability is inclusive of 25°C tolerance, operating temperature range, input voltage change, load change, aging, shock and vibration.
4
Standard LVCMOS frequencies include 10MHz, 12MHz, 12.288MHz, 16MHz, 20MHz, 24MHz, 24.576MHz, 25MHz, 33.333MHz, 40MHz, 48MHz,
50MHz, 100MHz, 125MHz and 156.25MHz.
5
Standard differential frequencies include 100MHz, 106.25MHz, 125MHz, 150MHz, 155.52MHz, 156.25MHz, 200MHz, 212.5MHz, 250MHz, 300MHz,
312.5MHz and 400MHz.
