ADH870S
ObsoleteDC to 20 GHz, MZ Optical Modulator Driver
Overview
- Wide Supply Range from +3.3V to +7V
- Adjustable Output Amplitude: 2.5 Vp-p to 8 Vp-p
- Low DC Power Consumption: 1 W for VOUT = 8 Vp-p at Vdd = +7V
- Low Additive RMS Jitter, < 300 fs
- Cross Point Adjustment
- 32 Lead 5 mm x 5 mm SMT package
- Screened with guidelines to MIL-PRF-38535, Class Level S
The ADH870S is a GaAs MMIC PHEMT MZ optical modulator driver that operates between DC and 20 GHz. The amplifier provides 17 dB of gain, 8 Vp-p saturated output swing and features output swing cross point adjustment. Gain flatness is excellent at ±0.5 dB as well as very low additive RMS jitter of 300 fs for 10 Gbps operation.
The ADH870S provides Metro and Long-Haul designers with scalable power dissipation for varying output drive requirements. (<0.4 W at VOUT = 3.6 Vp-p and < 1 W at VOUT = 8.5 Vp-p). The ADH870S has a very wide supply (Vdd) operating range from +3.3 V to +7 V, and the RF I/Os are internally matched to 50 Ohms.
