3 / 10 page 1.25Gbps/2.5Gbps, +3V to +5.5V, Low-Noise Transimpedance Preamplifiers for LANs _______________________________________________________________________________________ 3 Note 1: Source Capacitance represents the total capacitance at the IN pin during characterization of noise and bandwidth parame- ters. Figure 1 shows the typical source capacitance vs. reverse voltage for the photodiode used during characterization of TO-56 header packages. Noise and bandwidth will be affected by the source capacitance. See the Typical Operating Characteristics for more information. Note 2: Input-Referred Noise is calculated as RMS Output Noise / (Gain at f = 10MHz). Noise Density is (Input-Referred Noise) / √bandwidth. No external filters are used for the noise measurements. Note 3: Deterministic Jitter is measured with the K28.5 pattern applied to the input [00111110101100000101].
