Maxim Integrated 

Low-Power, 622Mbps Limiting Amplifiers

with Chatter-Free Power Detect for LANs

AC ELECTRICAL CHARACTERISTICS

(VCC = +4.5V to +5.5V, PECL outputs terminated with 50Ω to VCC - 2V, input 4mV to 2Vp-p, TA = -40°C to +85°C, unless otherwise

noted. Typical values are at VCC = +5.0V, TA = +25°C.) (Note 5)
