3.7. External I
It is possible to use an external I
installed in J20 and connect the external I
harness. Pins 4 and 6 can be driven as SCL and SDA, respectively.
3.8. Si5xx-PROG-EVB Digital Control Signal
One normally static digital input control signal routes to the Si5xx: Output Enable or OE. By default, the OE signal
is pulled HIGH on the Si5xx-PROG-EVB and may be pulled low by installing a jumper at J16.
3.9. Si5xx-PROG-EVB Voltage Control Signal
An external voltage control signal may be applied to the control voltage modulation input at the J12 header
(VCO_IN). This voltage supplies the control voltage or voltage modulation input to the DUT. J13 should be installed
in the 2-3 position.
3.10. Output Terminations
The Si5xx-PROG-EVB can support four different output formats: CMOS, LVPECL, LVDS, and HCSL. There are
output resistors that are needed to accompany each format. Table 5 shows which resistors are needed for each
output:
