TZA3019 - NXP

TZA3019 2.5 Gbits/s dual postamplifier with level detectors and 2 x 2 switch

The TZA3019 is a low gain postamplifier multiplexer with a dual RSSI and/or LOS detector that is designed for use in critical signal path control applications, such as loop-through, redundant channel switching or Wavelength Division Multiplexing (WDM). The signal path is unregistered, so no clock is required for the data inputs. The signal path is fully diff.

Features

• Dual postamplifier
• Single 3.3 V power supply
• Wideband operation from 50 kHz to 2.5 GHz (typical value)
• Fully differential
• Channels are delay matched
• On-chip DC-offset compensations without external capacitor
• Interfacing with positive or negative supplied logic
• Switching possibility between channels
• Positive Emitter Coupled Logic (PECL) or Current-Mode Logic (CML) compatible data outputs adjustable from 200 to 800 mV (p-p) single-ended
• Power-down capability for unused outputs and detectors
• Rise and fall times 80 ps (typical value)
• Possibility to invert the output of each.
