ICS2305

REV F 051310

DC Electrical Characteristics

ICS2305M-XX, VDD = 3.3 V ±10%, Ambient Temperature -40 to +85

° C(Industrial), (0-70° C Commercial)

Note 1: When there is no clock signal present at CLKIN, the ICS2305 will enter power down mode. The

PLL is stopped and the outputs are tri-state.

AC Electrical Characteristics

ICS2305M-1, VDD=3.3 V ±10%, Ambient temperature -40 to +85

° C(Industrial), (0-70° C Commercial)

Note 2: With VDD at a steady rate and valid input at CLKIN.
