EYE PATTERN CIRCUIT
Figure 14 is the eye pattern circuitry used in the
Z0220100ZCO modem evaluation board, and can be used
with modem components such as the ZiLOG Z02201 and
Z02201 that have an eye pattern interface. The Z02201 Eye
Pattern port consists of 3 signals:
Data (EYEOUT).
The most significant and least
significant bytes of this 16 bit word are the X and Y
coordinates respectively for the eye pattern display. Each
byte is most significant bit first.
Clock (EYECLK)
. Data is set on the rising edge of the
EYECLK
, and should be read on the falling edge.
Strobe (EYESTB).
This signal is active Low when the
data is valid.
Data is shifted through a pair of 8 bit serial-in parallel-out
shift registers (74HC594) in response to the falling edge of
EYECLK
, then latched into a pair of 8 bit DACs on the rising
edge of
EYESTB
. The output of these DACs can be viewed
on an oscilloscope in
X
–
Y
mode to see the received signal
quality.
