LTC1068 Series

Clock-Tunable, Quad

Second Order, Filter Building Blocks

FEATURES

DESCRIPTION

The LTC

1068 product family consists of four monolithic

clock-tunable filter building blocks. Each product contains

four matched, low noise, high accuracy 2nd order switched-

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). External resistors can modify the clock-

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.
