SONET/SDH TRANSMITTER & RECIEVER

°C, unless otherwise noted)

All parameters are specified over the operating case temperature.

Measurement conditions are at 2488.32Mb/s +/-20ppm, NRZ PN2

Vcc=+5.0V+/-5%, Vee=-5.2V+/-5%, and for Transmitter.

note : Vcc-Vee ; with Vcc at +5V Vee must be at 0V ; with Vee at -5.5V Vcc must be at 0V

note : Internally AC coupled with 50ohm internal termination

note 1: Vcc-Vee ; with Vcc at +5V Vee must be at 0V ; with Vee at -5.5V Vcc must be at 0V

note 2: Internally AC coupled with 50ohm internal termination

note 3: This sensitivity is achieved by applying at minimum either a 0.6Vpp signal on one input while

the other input is tied to ground or by applying two complementary 0.3Vpp signal on both inputs.

note 4: when Vcc at +5V and Vee at 0V

note 5: This voltage is measured taking Vee as reference.

note 6: At the moment the jitter bandwidth performance according GR-253/ITU-T G958 is not met atthe receiver interface level.

Additional clock filtering is supposed to be done at lower data rates.

Jitter transfer bandwidth will be defined at this level which is a parameter of the whole network element and not of the

receiver element.

A further version is under investigation to met simultaneously all the GR-253/ITU-T G958 jitter specifications at the

physical interface level.
