ICS87008I Description
The ICS87008I is a low skew, 1:8 LVCMOS/LVTTL Clock Generator. The device has 2 banks of 4 outputs and each bank can be independently selected for ÷1 or ÷2 frequency operation. Each bank also has its own power supply pins so that the banks can operate at the following different voltage levels:.
