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.

Logic output level note 6 - TTL compatible -
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.
