674R-01ILFT集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 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.
