PLD implements fast four-phase clock generator - 10/27/94 EDN Design Idea The circuit in Fig 1a can clock pipelined logic in PLDs by an
external agent at one-half the usual frequency. You can use this circuit when designing pipelined ALUs and
switched-capacitor circuits. I used this circuit to drive a 40M-sample/sec CMOS flash. . . [by Said Jackson,

PLD Solves RS-232C Compatibility Problem - 01/19/95 EDN Design Idea RS-232C communication has many nasty, low-level problems. For
example, converting one form of RS-232C bit stream to another is frustrating without a general-purpose UART. The
circuit in Fig 1 strips the parity bit out of an RS-232C bit stream. The input is a 9600-baud, 8-data bit,
odd-parity, and one-stop-bit (9600, 8, O, 1) stream. The output is a no- parity (9600, 8, N, 1) stream. . . .

PLL
forms simple MSK demodulator - 12/17/98 EDN Design Idea
(File contains many circuits. Scroll to find this one. ) In minimum-shift-keying (MSK) signaling, two
frequencies that differ by the bit rate represent a one bit and a zero bit. Normally, the frequency shift occurs
at the peak of a cycle, so that neither the amplitude nor the slope of the waveform shows a discontinuity. We
needed to transmit 300-baud ASCII text using ultrasonic transducers. These devices have a very narrow bandwidth
around their 25-kHz resonant frequency, . . . [by Tom Napier, North Wales, PA]
PLL IC Forms Simple Digital Phase Shifter - 01/04/96 EDN Design Idea A phase shifter is a vital block in some signal-processing and
clock-distribution applications. Another important application is in benchmarking digital phase detectors. The

PLL synchronizes
power-supply IC - 07/16/98 EDN Design Idea (File has
several circuit ideas. Scroll to find this one. ) It is often desirable to synchronize a switching power supply
to a system clock or to a second supply. If the power-supply controller has no synchronization pin, you can add a
low-value resistor in series with the oscillator. . . [by Kurk Mathews, Linear Technology Corp, Milpitas, CA]
