4 / 8 page MAX2740 Evaluation Kit 4 _______________________________________________________________________________________ VGA and FGA The inputs and outputs of both circuits are differential. The VGA has a useful gain-control range of >50dB. The FGA was designed to deliver 40dB of differential gain at the second IF frequency of 15.42MHz. In the appli- cation, the FGA differential inputs are received from the VGA outputs through a balanced lowpass filter circuit. The FGA’s differential output is designed to drive a dig- itizer with a typical load impedance of 4k Ω differential. PC Board Layout/Construction The MAX2740 EV kit can serve as a board layout guide. Keep PC board trace lengths as short as possible to minimize parasitics. Keep decoupling capacitors close to the device, with a low inductance via connection to the ground plane. The GLSOUT signal must not be routed parallel to the REF input to avoid loss of frequen- cy lock due to coupling between the two signals. The MAX2740 EV kit PC board uses 14mil-wide traces for 50 Ω traces. The PC board has an 8mil layer profile to the ground plane on FR4, with a dielectric constant of 4.5, and 75mil trace-to-ground-plane spacing. |
