? gigabit interface converters (gbic) mgbc-20-6-x-x copper fibre channel termination circuits inputs to the mgbc-20 transmitter are ac coupled and internally terminated through 75 ohms to ac ground. these modules can oper ate with pecl or ecl logic levels. the input signal must have at least a 650 mv differential signal swing. output from the receiver section of the module is also ac coupled and is capable of driving a 150 ohm differential load. different termination strategies may be required depending on th e particular serializer/ deserializer chip set used. the mgbc-20 product family is designed with ac coupled data inputs and outputs which provides the following advantages: n close positioning of serdes with respect to transceiver; allows for shorter line lengths and at gigabit speeds reduces emi. n minimum number of external components. n internal termination reduces the potential for unterminated stubs which would otherwise increase jitter and reduce transmission margin. subsequently, this affords the customer the ability to optimally locate the serdes as close to the mgbc-20 as possible and save valuable real estate. at gigabit rates this can provide a significant advantage resulting in better transmission performance and accordingly better s ignal integrity. figure 1 illustrates the recommended transmit and receive data line terminations. performance specifications - electrical ta = 25 c, vcc = 5.0 v r e t e m a r a pl o b m y sn i mp y tx a ms t i n us e t o n e t a r r o r r e t i b r e b2 1 - e 1n i m r p @ t i b / s r o r r e t n e r r u c y l p p u s c c i0 5 1a mv 5 . 5 < c c v < v 5 . 4 , c 0 7 < a t < c 0 t n e r r u c e g r u se g r u s i0 3 +a me u l a v e t a t s y d a e t s e v o b a e g r u s r e t t i m s n a r t ) l a i t n e r e f f i d ( t u p n i l c e p0 5 10 2 70 0 0 2p p v ms t u p n i d e l p u o c c a ) l a i t n e r e f f i d ( e c n a d e p m i t u p n in i z5 3 10 5 15 6 1s m h oc d @ s m h o k 0 0 1 > n i r h g i h - e g a t l o v t u p n i e l b a s i d _ x th i v2 3 . 0 + c c vv w o l - e g a t l o v t u p n i e l b a s i d _ x tl i v0 8 . 0v r e v i e c e r ) l a i t n e r e f f i d ( t u p t u o l c e p0 0 40 5 70 0 6 1p p v ms t u p t u o d e l p u o c c a ) l a i t n e r e f f i d ( e c n a d e p m i t u p t u ot u o z5 3 10 5 15 6 1s m h o h g i h - e g a t l o v t u p t u o s o l _ x rh o r v6 . 2 - c c vc c vv a 0 5 2 = o l w o l - e g a t l o v t u p t u o s o l _ x rl o r v0 5 . 0v a m 0 . 2 - = o l ] k p - k p [ r e t t i j l a t o tj t0 0 5s pe t o n e e s e m i t l l a f / e s i r t u p t u of t , r t0 0 10 5 3s p% 0 8 - % 0 2 ) 2 : 0 ( f e d _ d o m h o v5 . 2v d i l a i r e s h t i w l o v0 5 . 0v c nk 0 0 1s m h od n g t / d n g r o t d e r u s a e m
