The TNETA1622 recovers an embedded clock  
signal from a 622.08-Mbit/s STS-12/STM-4  
nonreturn-to-zero (NRZ) data stream using a  
frequency/phase-locked loop. The device  
accepts PECL (ECL signals referenced to 5 V  
instead of GND) input-voltage levels. The  
recovered clock and data outputs are PECL  
compatible. The serial data input and recovered  
clock and data outputs are differential to provide  
maximum noise immunity.

NC − No internal connection  
The TNETA1622 requires only a positive 5-V supply (5 V 5%) for operation. The TNETA1622 is characterized  
for operation over a temperature range of 40°C to 85°C.
