description
The TNETA1611 is an STS-12c/STM-4 receiver/transmitter that performs data serialization and deserialization
for 622.08-Mbit/s data streams used in STS-12c/STM-4 systems. On the receive side, bit alignment is
performed on the serial input data such that parallel data is output on SONET/SDH byte boundaries. The
TNETA1611 conforms to applicable SONET/SDH standards and can simultaneously convert the serial data to
byte-wide data and the byte-wide data to serial data. Clock and data loopback features increase versatility. The
TNETA1611 is designed for operation with a heat sink over a temperature range of –40
°
C to 85
°
C.
