1Gbps to 14Gbps, SFP+ Multirate Limiting
Amplifier and VCSEL Driver
Typical Operating Characteristics—Limiting Amplifier
(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.)
