ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C; VDD = VDD(HS) = 3.3V, IS = 24mA; IM = 12mA (IMPP = 24mA); 49.9Ω, 1%

resistor from SRC (Pin 14) to MODA (Pin 11); 50

Ω, 1% load AC coupled to MODB (Pin 10); 10nF, 10% capacitor from SRC (Pin 14) to

VSS; Cml_en = 0, Lpc_en = 1, transmitter enabled, unless otherwise noted. Test circuit in Figure 5.
