Maxim Integrated 

1Gbps to 14Gbps, SFP+ Multirate Limiting

Amplifier and VCSEL Driver

Typical Operating Characteristics—Limiting Amplifier (continued)

(VCC = 3.3V, TA = +25°C, unless otherwise specified. Figure 1 shows the typical setup used for measurements. Registers are set to

default values unless otherwise noted, and the 3-wire interface is static during measurements. For testing, the RATE_SEL bit was

used and the RSEL pin was left open.)
