Hardware Description
The evaluation board comes with a cable for connecting to
the printer port of a PC. The silk screen and cable diagram for
the evaluation board are shown below. The board sche-
matic are shown on page 3
The ADF7010 should be supplied with an external supply
of 2.3V to 3.6V. There is an on-board 19.2 MHz AT
crystal from FOX. The crystal combined with 33pF shunt
capacitors provide the low cost frequency reference for the
PLL. The loop filter is designed for use with a 19.2MHz
PFD frequency. This means that the R divide should be
set to 1. The N-divide should be set to whatever factor is
required to multiply the 19.2MHz PFD frequency up to
the required output frequency.
The necessary SMA connectors are included to interface
the part to the measurement instrument. (Normally a spec-
trum analyzer). Care should be taken to ensure that no
DC level exists at the RFout SMA - DC into the front of
measurement equipment will damage the input. There is
a 150pF ac coupling capacitor at the output.
The parallel port has 5V voltage levels, so there is a volt-
age divider to bring this down to levels acceptable to the
ADF7010.
