2 Signal Path and Control Circuitry
The CDCLVC1112 EVM supports single-ended inputs up to 250MHz. For more information about the
CDCLVC1112, see the CDCLVC1112 product data sheet available for download from the TI web site
(www.ti.com).
3 Getting Started
The CDCLVC1112EVM has self-explanatory labeling and uses similar naming conventions as the
CDCLVC1112 product datasheet. In this user’s guide, all words in boldface and italic print reflect the
actual labeling on the EVM.
4 Power-Supply Connections
Connect the power-supply source to the banana plug labeled VDD (P1), and connect the ground of the
power-supply source to GND (P2). There are decoupling capacitors and a ferrite bead to isolate the EVM
power from the CDCLVC1112 device power pins.
The CDCLVC1112EVM can use a supply voltage 3.0 to 3.6 V.
5 Enabling/Disabling the Outputs
The Enable pin of the CDCLVC1112 can be controlled using jumper J21 or the SMA J2. The J2 connector
is not soldered on the CDCLVC1112EVM but can be soldered if needed. Check the BOM section for part
ordering information.
6 Output Clock
The CDCLVC1112 generates twelve LVCMOS outputs. The outputs can be loaded using the pull-up and
pull-down footprints. No resistor has been soldered in those footprints.
