Either one of two loop filters can be selected by shorting either R69 or R72. More info
about the loop filter can be found in the General Description. The second loop filter on
the bottom of the board is unpopulated for customer use.
Test points for each of the uWire lines are scattered in the lower left corner of the board
and include: GOE_TP, DATAuWire, CLKuWire, LEuWire, SYNC_TP, and LD_TP.
Ground is located on the unstuffed 10 pin header on the left side of the board.
Ground is located on the GND_tp2 in the upper left corner of the board and GND_tp1
located to the right of the Vcc SMA connector.
Ground is located on the bottom side of the board on each pad of the unstuffed 10 pin
header GND_J2.
Vcc is located on the unstuffed 10 pin header on the upper left side of the board.
Vcc is located on VccPlane test point located to the right of the Vcc SMA.
Vcc is located on the bottom side of the board on each pad of the unstuffed 10 pin
header VCC_J2
When changing the OSCin frequency, the OSCin frequency register needs to match.
Toggle the SYNC* pin to synchronize the clock outputs when in divided mode. If the
SYNC* pin is low, divided outputs will not oscillate but the bypassed outputs will continue
to oscillate.
For both loop filters, a helper silkscreen is offset from the loop filters to help identify the
components according to National Semiconductor’s traditional reference designators
associated with loop filters.
The silk screen Fin/Fin* designates the FBCLKin/FBCLKin* port.
