ICS674-01
REV H 051310
Description
The ICS674-01 consists of two 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.
