Note 7:
Offset error is the offset voltage measured from –0.5 LSB when may cause permanent damage to the device. Exposure to any Absolute the output code flickers between 00 0000 0000 0000 and 11 1111 1111 Maximum Rating condition for extended periods may affect device 1111 in 2’s complement output mode. reliability and lifetime.
Note 8:
Guaranteed by design, not subject to test.
Note 2:
All voltage values are with respect to GND (unless otherwise

When these pin voltages are taken below GND or above VDD, they ENC+/ENC– = 2VP-P sine wave, input range = 2VP-P with differential will be clamped by internal diodes. This product can handle input currents drive, unless otherwise noted. The supply current and power dissipation of greater than 100mA below GND or above VDD without latchup. specifications are totals for the entire device, not per channel.

Note 11:
The maximum sampling frequency depends on the speed grade they will not be clamped by internal diodes. This product can handle input of the part and also which serialization mode is used. The maximum serial currents of greater than 100mA below GND without latchup. data rate is 1000Mbps so tSER must be greater than or equal to 1ns.

Note 12:
Near-channel crosstalk refers to Ch. 1 to Ch.2, and Ch.7 to Ch.8. (LTM9010), or 80MHz (LTM9009), 2-lane output mode, differential ENC+/ Far-channel crosstalk refers to Ch.1 to Ch.7, Ch.1 to Ch.8, Ch.2 to Ch.7, and ENC– = 2VP-P sine wave, input range = 2VP-P with differential drive, unless Ch.2 to Ch.8. otherwise noted.
Note 6:
Integral nonlinearity is defined as the deviation of a code from a best fit straight line to the transfer curve. The deviation is measured from the center of the quantization band.
