ELECTRICAL CHARACTERISTICS (continued)
(VCC = 2.85V to 3.63V, TA = -40°C to +85°C, CML receiver output load is AC-coupled to differential 100
Ω, CAZ = 1nF, transmitter out-
put load is AC-coupled to differential 100
Ω (see Figure 1), typical values are at +25°C, VCC = 3.3V, IBIAS = 6mA, IMOD = 6mA, unless
otherwise specified. Registers are set to default values unless otherwise noted, and the 3-wire interface is static during measure-
ments. For testing, the MODE_SEL bit was used and the MSEL pin was left open.)

Note 1: Supply current is measured with unterminated receiver CML output or with AC-coupled Rx output termination. The Tx out-
put and the bias current output must be connected to a separate supply in order to remove the modulation/bias current
portion from the supply current. BIAS must be connected to 2.0V. TOUT+/- must be connected through 50
Ω load resistors
to a separate supply voltage.
Note 2: Guaranteed by design and characterization, TA = -40°C to +95°C.
Note 3: The data input transition time is controlled by a 4th-order Bessel filter with -3dB frequency = 0.75 x data rate. The determin-
istic jitter caused by this filter is not included in the DJ generation specifications.
Note 4: Test pattern is 00001111 at 4.25Gbps for MODE_SEL = 0. Test pattern is 00001111 at 8.5Gbps for MODE_SEL = 1.
