Product Details
The EVAL-ADN4680EEBZ allows quick and easy evaluation of the ADN4680E 250 Mbps, half-duplex, quad multipoint, low voltage differential signaling (M-LVDS) transceivers. The EVALADN4680EEBZ allows the input and output functions of each transceiver to be exercised without the need for external components.
Subminiature A (SMA) connectors provide convenient connections for high speed logic and the M-LVDS bus signals. Screw terminal blocks are available to access power, ground, and digital signals. Jumper options allow control of each transceivers driver and receiver enable pins, each transceivers fail-safe functionality, and the global power-down mode.
The EVAL-ADN4680EEBZ is optimized for high speed signaling. The differential M-LVDS signal traces on the board are routed as a length matched 100 Ω differential pair. The DIx digital input and ROx receiver output are also length matched and routed with a controlled 50 Ω impedance to ground. The EVAL-ADN4680EEBZ features a solid ground and power plane for optimum power integrity.
The EVAL-ADN4680EEBZ has a footprint for the ADN4680E transceivers in a 7 mm × 7 mm, 48-lead LFCSP. For full details on the ADN4680E, see the ADN4680E data sheet, which must be used in conjunction with the user guide when using the EVAL-ADN4680EEBZ.
