The EV kit enables testing of all the device’s functions. SMA connectors with 50Ω controlled impedance connections to the MAX3882 are provided for the NRZ data input and LVDS data outputs, as well as system loopback functions. The 50Ω connectors allow for direct connection with high-speed test equipment. _________________________Features MAX3882 Evaluation Kit Evaluates: MAX3882 _______________ Detailed Description The MAX3882 EV Kit is fully assembled and factory tested. It enables testing of all MAX3882 functions. Connections The MAX3882 EV Kit provides on-board connectors for all data and clock I/O ports. The serial data and system loopback inputs (SDI+ and SLBI+) can be connected directly to a 50Ω source. Jumpers PLL frequency lock condition can be monitored at the high-impedance LOL test point. A TTL high for LOL (LED off) indicates PLL frequency lock. A TTL low for LOL (LED on) indicates loss-of-lock. 2 _________________________________________________________________________________________ MAX3882 Evaluation Kit Evaluates: MAX3882 Figure 1.
