MAX9176/MAX9177 19-2757 Rev 0 1/03 670MHz LVDS-to-LVDS and Anything-to-LVDS 2:1 Multiplexers General Description Features The MAX9176/MAX9177 are 670MHz, low-jitter, low- 1.0ps Jitter (max) at 670MHz (RMS) skew 2:1 multiplexers ideal for protection switching, 68ps Jitter at 800Mbps Data Rate (P-P) loopback, and clock distribution. The devices feature ultra-low 68ps peak-to-peak deterministic jitter that 3.3V Supply ensures reliable operation in high-speed links that are LVDS Fail-Safe Inputs (MAX9176) highly sensitive to timing errors. Anything Inputs (MAX9177) Accept The MAX9176 has fail-safe LVDS inputs and an LVDS output. The MAX9177 has anything differential inputs CML/LVDS/LVPECL (CML/LVDS/LVPECL) and an LVDS output. The output Select and Power-Down Inputs Tolerate -1.0V can be put into high impedance using the power-down and V + 1.0V CC input. The MAX9176 features fail-safe circuits that drive the output high when a selected input is open, undriven Low-Power CMOS Design and shorted, or undriven and terminated. The MAX9177 10-Lead MAX and QFN Packages has bias circuits that force the output high when a selected input is open. The mux select and power- -40C to +85C Operating Temperature Range down inputs are compatible with standard LVTTL/ Conform to ANSI TIA/EIA-644 LVDS Standard LVCMOS logic. IEC61000-4-2 Level 4 ESD Rating The select and power-down inputs tolerate undershoot of -1V and overshoot of V + 1V. The MAX9176/ CC MAX9177 are available in 10-pin MAX and 10-lead thin QFN packages, and operate from a single 3.3V supply over the -40C to +85C temperature range.
