Summary:The CDF calorimetry readout module, called the ADMEM, has been
designed to contain both the analog circuitry which digitizes the
phototube charge pulses, and the digital logic which supports the
readout of the results through the CDF Run 2 DAQ system. The ADMEM
module is a 9U×400 mm VMEbus module, which is housed in a CDF
VMEbus VIPPA crate. The ADMEM must support near deadtimeless operation,
with data being digitized and stored for possible readout every 132 ns
or 7.6 MHz. This paper will discuss the implementation of the analog and
digital portions of the ADMEM module, and how the board was laid out to
avoid the coupling of digital noise into the analog circuitry
