• Wear a conductive wrist strap in series with a 100k resistor to ground. (Replacement wrist straps that connect to the bench top covering are Motorola part number 4280385A59). • Do not wear nylon clothing while handling CMOS devices. • Do not insert or remove CMOS devices with power applied. Check all power supplies used for testing CMOS devices to be certain that there are no voltage transients present.

All manuals and user guides at all-guides.com 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry 11-5 11.4.2 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25kHz or 5kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator.
