• Manufacturer Part Number: MAX3941
• Description: 10Gbps EAM Driver with Integrated Bias Network
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
otherwise noted.)
Note 1: Supply current remains elevated once the retiming function is enabled. Power must be cycled to reduce supply
Note 2: Power-supply noise rejection is specified as PSNR = 20log(V
Note 3: For DATA+, DATA-, CLK+, and CLK-.
Note 4: CLK input characterized at 10.7Gbps.
Note 5: R
Note 6: Guaranteed by design and characterization using the circuit shown in Figure 4.
Note 7: R
Note 8: 50Ω load, characterized at 10.7Gbps with a 1111 1111 0000 0000 pattern.
Note 9: Deterministic jitter is defined as the arithmetic sum of pulse-width distortion (PWD) and pattern-dependent jitter (PDJ).
Note 10: For MODEN and PLRT.
