4.1.3.2 OE and ZOUT_SEL Pin Control

Low and High voltage levels can be set on all the pins using the GUI without the need of on-board headers. If on-board jumper headers are used, set all the OE# and ZOUT_SEL pins to Hi-Z using the All Hi-Z button under the OE & ZOUT_SEL Pin Control.

Table 4-5 OE# Pins
Pin Level Function
Low LMKDB1204 has CLK# enabled.
High LMKDB1204 has CLK# disabled.
Hi-Z When Hi-Z is selected, on-board header jumper can be used to force external voltages on the pin. For OE3# (JP5),R52 must be depopulated to certify proper operation. If SMBus mode needs to be activated after removing R52, then on-board header jumper JP5 needs to be set to high.
Table 4-6 ZOUT_SEL
Pin Level Function
Low LMKDB1204 has 85Ω output termination.
High LMKDB1204 has 100Ω output termination.
Hi-Z When Hi-Z is selected, on-board header jumper can be used to force external voltages on the pin.
