ICS674R-01IT Datasheet PDF - Integrated Circuit Systems

Description
The ICS674-01 consists of 2 separate  configurable dividers.  The A Divider is a 7 bit  divider and can divide by 3 to 129. The  B Divider consists of a 9 bit divider followed by a  post divider.  The 9 bit divider can divide by 12  to 519.  The post divider has eight settings of 1, 2, 4, 5, 6, 7, 8 and 10 giving a maximum total  divide of 5190.  The A and B Dividers can be  cascaded to give a maximum divide of 669510.   The ICS674-01 supports the ICS673 PLL  Building Block and enables the user to build a full  custom PLL synthesizer.
