PMAC Lite E-Point Descriptions 31
E98: DAC/ADC Clock Frequency Control
E Point and
Physical Layout
Location Description Default
E98 F3 Jump 1-2 to provide a 2.45 MHz DCLK signal
to DACs and ADCs.
Jump 2-3 to provide a 1.22 MHz DCLK signal
to DACs and ADCs. Important for high
accuracy A/D conversion on Acc-28.
Note : This also divides the phase and servo
clock frequencies in half.

E Point and
Physical Layout
Location Description Default
E101 H1
CAUTION:
The jumper setting must match the type of
driver IC, or damage to the IC will result.
Jump pin 1 to 2 to apply +V (12V to 24V) to
pin 10 of U54 (should be ULN2803A for sink
output configuration) for AENA1-4 and EQU1-
4 flag outputs.
Jump pin 2 to 3 to apply AGND to pin 10 of
U54 (should be UDN2981A for source output
configuration) for AENA1-4 and EQU1-4 flag
outputs.
1-2 Jumper installed
