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 ....
