2.2 AC Electrical Characteristics
Table 2-3: AC Electrical Characteristics
VCC = +2.8V to +3.47V, TC = -40°C to 95°C. Typical values are at VCC = +3.3V and TA = 25°C, unless otherwise specified.
Note: mVppd refers to mV peak-to-peak differential value.

Notes:
1. At jitter frequencies <120kHz the GN2014A jitter tolerance performance exceeds the XFI module transmitter input telecom sinusoidal jitter
tolerance specifications (XFP MSA Revision 4.0, Figure 16).
2. At 5.35GHz (dielectric loss)
3. 8MHz bandwidth can be obtained using the loop filter components R1, R2. The values for these components should be selected at module
level.
