NCS25S10数据手册NewCoSemi中文资料规格书

描述 Description

NCS25S10 is a highly versatile, high-performance, low-power clock fanout buffer which can distribute up to ten low-jitter LVCMOS clock outputs from one of the selectable three inputs which are primary and secondary inputs supporting both differential and single-ended clocks, and crystal input. NCS25S10 can operate up to 200MHz from primary or secondary inputs, and 8MHz to 50MHz from crystal input.NCS25S10 supports synchronous output enable for glitch-free operation.\r
\r
The primary/secondary and crystal inputs are supplied by core voltage VDD which can be set to 2.5V or 3.3V, while the 10 output drivers are separated into two groups, DRV CKY0-CKY4 are supplied by VDDOA, and CKY5-CKY9 are supplied by VDDOB. VDDOA and VDDOB can be set to the same supply from 1.5V, 1.8V, 2.5V, 3.3V, or set individually.\r
\r
NCS25S10 can be easily configured through pin programming. The overall additive jitter performance is 30 fs (typical).
