IDT, Integrated Device Technology Inc 87972DYILFT

Description
The 879721 is a low skew, LVCMOS/LVTTL Clock Generator with three selectable inputs and fourteen LVCMOS/LVTTL outputs. It is a highly flexible device that can be used to generate clocks for a system using a crystal oscillator input or LVCMOS/LVTTL reference clock inputs. The device can be configured to generate up to three different frequencies among the three output banks. It also has a QSYNC output that can be used for system synchronization purposes.
