Use a PC's parallel Port to program a clock source - 12/07/04 EDN-Design Ideas:
This Design Idea shows how you can use Linear Technology's LTC6903 programmable
oscillator as a clock source for direct-digital synthesis, data conversion,
switched-capacitor filtering, clock, and voltage-controlled oscillator circuits. The
LTC6903 operates from 2.7 to 5.5V with modest power consumption and can produce clock
signals at frequencies of 1 kHz to 68 MHz.....(design idea added 1/05) |
