Datasheet
1. General description
2. Features
The TZA3054A is a highly sensitive A-rate™ Limiting amplifier featuring ACE (Automatic
Current Engine) functionality, Logarithmic Level Detect (LLD), Loss-of-Signal (LOS)
detector and output jam function. The ACE functionality provides a limiting amplifier which
achieves optimum performance (sensitivity, bandwidth, jitter and output eye pattern) for
any bit rate with very low power consumption. This is achieved through automatic
adjustment of the input bandwidth and the output slew rate by using built-in performance
monitors. Manual adjustment is possible by programming the I
The integrated I
which minimizes the number of external connections and external components needed.
Adjustment of the LOS threshold can be done either via the I
resistor. The output amplitude is selectable between a high or low value, or adjustable via
the I
LLD, or by a binary value of an I
the internal supply voltage and an external voltage can all be monitored through a built-in
Analog-to-Digital Converter (ADC) which supports several diagnostic functions.
These features make the TZA3054A ideally suited for application in modules, including
Small Form Factor (SFF/SFP/iSFP) modules.
The TZA3054A comes in a compact 3
pad serving as the main ground connection.
