that ensures compliance to ETSI 300 166 return loss
requirement.
TTL compatible dual rail transmit data signals are
supplied to TXPOS and TXNEG inputs. The transmitter
differentialoutputs TTIP andTRING are connectedtothe
outputtransformerprimary throughseries 9.1
resistors.
All the four transmitters can be operated in two distinct
modes ofoperationreferredtoas “clocked”or“clockless”
modes. The operationalmode is selectedautomatically
basedonthe signalprovidedtoTXCLK input. Ifa clock is
present at this pin, the transmitter detects its presence
and operates in the clocked mode. In this mode, the
transmit input should be supplied with full-width NRZ
pulses. Ifa clock is notpresentatthe TXCLK input(pinis
leftopen), the partoperates inthe clockless mode. Inthis
mode, RZ data should be supplied to the device. Each
transmitchannelofXRT5894 has a duty cycle correction
circuitry.
This enables the device to produce output
bipolar pulses fully compliant with G.703 despite having
TXCLK signal with 30% to 70% duty cycle.
