It is used to extend the reach and robustness of long, lossy, crosstalk-impaired high-speed serial links while achieving a bit error rate (BER) of 10-15 or less. 1 • • • • • • • • • • • • • • Octal-Channel Multi-Rate Retimer with Integrated Signal Conditioning All Channels Lock Independently from 20.2 Gbps to 28.4 Gbps (Including Sub-Rates Like 10.1376 Gbps, 10.3125 Gbps, 12.5 Gbps, and More) Ultra-Low Latency: 10 MHz, sinusoidal (1) 10 mVpp TrampVDD VDD supply ramp time, from 0 V to 2.375 V 150 TJ Operating junction temperature -40 110 ºC TA Operating ambient temperature -40 85 (2) ºC VIO2.5V 2.5 V I/O voltage (LVCMOS, CMOS and Analog) 2.375 2.625 V VIO3.3V,INT_N Open Drain LVCMOS I/O voltage (INT_N) 3.6 V VIO3.3V Open Drain LVCMOS I/O voltage (SDA, SDC) 3.6 V (1) (2) μs 2.375 Steps must be taken to ensure the combined AC plus DC supply noise meets the specified VDD supply voltage limits. Steps must be taken to ensure the operating junction temperature range and ambient temperature stay-in-lock range (TEMPLOCK+, TEMPLOCK-) are met.
