MK1493-05 REV J 051310
Electrical Characteristics - DC
Unless stated otherwise, VDD = 3.3 V ±5%, Ambient Temperature -40 to +85° C
1
Includes ±50K ohm internal.
2
Single edge is monotonic when transitioning through region.
3
Inputs with pull-ups/-downs are not included.
4
Internal leakage to ground is less than equal to 5 uA to ensure high level if input is floating.
5
Configuration is Rr=475 ohms at 1%. Iref=2.32 mA. Iref=VDD/(3 x Rr).
Electrical Characteristics - CLKIN/REFOUT
Unless stated otherwise, VDD = 3.3 V ±5%, Ambient Temperature -40 to +85° C
