LN1A345

LN1A345 2mbps-200mbps With Signal Loss Detection TTL / CMOS Limiting Amplifier ■ Description LN1A345 limiting amplifier functions as data quantizer, the amplifier can accept a wide input voltage range and provides TTL/ CMOS output voltage. LN1A345 integrates a power detector, CMOS / TTL signal loss (LOS) output indicates the input power is dropped to the following programmable threshold. Squelch function of the data in the LOS state outputs remain in a static level. SW pin can control the level of high and low quiescent state. LN1A345 work at +5.0 V or +3.3 V single power supply, the working temperature range -40°C to +85°C, provides 16-pin TSSOP package. ■ Applications  2Mbps-200Mbps PDH ■Typical Operating Circuit ■ Features  High Sensitivity  Wide bandwidth  TTL / CMOS output  Programmable signal loss detection  Controlable the data output level Squelch level  3.3V, 5V compatible ■ Package  TSSOP-16 ■ Recommended Operating Conditions Paramete...
