TYPICAL APPLICATION
DESCRIPTION
Clock-Tunable, Quad
Second Order, Filter Building Blocks
The LTC1068 product family consists of four monolithic
clock-tunable filter building blocks. Each product contains
fourmatched,lownoise,highaccuracy2ndorderswitched-
capacitor filter sections. An external clock tunes the center
frequency of each 2nd order filter section. The LTC1068
products differ only in their clock-to-center frequency
ratio. The clock-to-center frequency ratio is set to 200:1
(LTC1068-200), 100:1 (LTC1068), 50:1 (LTC1068-50) or
25:1(LTC1068-25).Externalresistorscanmodifytheclock-
to-center frequency ratio. High performance, quad 2nd
order, dual 4th order or 8th order filters can be designed
with an LTC1068 family product. Designing filters with an
LTC1068 product is fully supported by FilterCAD filter
design software for Windows.
The LTC1068 products are available in a 28-pin SSOP
surface mount package. A customized version of an
LTC1068 family product can be obtained in a 16-lead SO
package with internal thin-film resistors. Please contact
LTC Marketing for details.
