D602 3V, 6GHz Divide-by-2 Static Prescaler Final Applications Product Description The D602 is a SiGe divide-by-2 low noise static prescaler capable of operation up to 6.0 GHz. The D602 operates over a wide range of input frequencies and levels, and provides differential outputs for low noise operation with the common PLL style frequency synthesizer ICs. 5GHz WLAN, IEEE 802.11a and HIPERLAN VSAT at 3.6 to 4.2 GHz Satellite Communications at 4.5 to 4.8 GHz 5 Gbps Clock Generator The static nature of the prescaler prevents spurious generation. Features The D602 prescaler can operate from either a single positive or single negative supply with power down mode for low standby power consumption.

Self oscillation can be eliminated by powering down the prescaler, or applying a differential DC input voltage (a 47kΩ resistor placed between pin 3 and VCC). (4) This power is delivered to a 50Ω load. It excludes the power dissipated in the external pull-up resistors.
