ADH871S

The ADH871S is a GaAs MMIC PHEMT EA optical modulator driver that operates between DC and 20 GHz and provides 15 dB of gain. The output swing cross point is adjustable and saturated output swing is 4 Vp-p. Gain flatness is excellent at 0.5 dB as well as very low additive RMS jitter of 300 fs for 10 Gbps operation.

The ADH871S provides VSR and Gigabit Ethernet designers with scalable power dissipation for varying output drive requirements (<0.25 W at VOUT = 2.5 Vp-p and <0.6 W at VOUT = 4 Vp-p). The ADH871S has a very wide supply (Vdd) operating range from +5V to +8V and the I/Os are internally matched to 50 Ohms.
