Limiting Amplifiers with Loss-of-Signal Detector
ELECTRICAL CHARACTERISTICS—MAX3964AETP
(VCC = +3.0V to +5.5V, PECL outputs terminated with 50Ω to (VCC - 2V), TA = -40°C to +85°C. Typical values measured at VCC =
+3.3V and TA = +25°C, unless otherwise noted.)

Note 1: Dice are tested and guaranteed at TA = +25°C only.
Note 2: LOS hysteresis = 20log(VLOS-DEASSERT / VLOS-ASSERT).
Note 3: Voltage measurements are relative to supply voltage (VCC).
Note 4: PWD = [(width of wider pulse) - (width of narrower pulse)] / 2, measured with 100Mbps 1-0 pattern.
Typical Operating Characteristics
(MAX3964A EV kit, VCC = +3.3V, decibels (dB) calculated as 20 log ∆V, PECL outputs terminated with 50Ω to (VCC - 2V), TA = +25°C,
unless otherwise noted.)
