Description
No Connect. This pin should be left open.
Ground pin. Ground pattern on the board
should be as wide as possible to reduce
ground impedance.
Input signal pin. DC blocking capacitor
required (100 pF typical).
Power supply pin. Bypassing is required.
Ground pin.
Divided frequency output pin. DC blocking
capacitor required (100 pF typical).
Device Functional Considerations
The PE3511 divides an input signal, up to a
frequency of 1500 MHz, by a factor of two thereby
producing an output frequency at half the input
frequency. To work properly with low impedance,
ground referenced interfaces, the input and output
signals (pins 3 & 6) must be AC coupled via an
external capacitor, as shown in the test circuit in
Figure 4.
The ground pattern on the board should be made
as wide as possible to minimize ground
impedance. See Figure 9 for a layout example.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
