Realtime clock Chip Makes Lowpower Oscillator: 11/23/00 EDN-Design Ideas /
(added 6/06) Many systems use watch-crystal-based, 32.768-kHz oscillators. In
battery-powered designs, the 32-kHz oscillator may consume a fairly high percentage of
the total power budget. Reduced power consumption equates to longer battery life,
smaller batteries, and smaller products. Ricoh (www.ricoh.com) manufactures more than
10.... |

System Implements Digital Clock Modulation : 10/28/04 EDN Design Ideas
/ (added 11/05) In spread-spectrum and direct-sequence receivers, it's often
necessary to change the frequency of the clock oscillator, and thus the spreading-code
clock, to lock the receiver's reference pseudorandom-noise code to the incoming code.
The original design used a VCXO (voltage-controlled crystal oscillator) for this
function, but .... |
