A product Line of Diodes Incorporated PI6C5912016-01 16 Output LVPECL Fanout Buffer Features Description 16 Differential LVPECL outputs e PTh I6C5912016-01 is a high performance LVPECL fanout buf - fer device which supports up to 2GHz frequency. This device is 2 Selectable reference inputs support either single-ended ideal for systems that need to distribute low jitter LVPECL clock or differential signals to multiple destinations. Up to 2GHz output frequency Ultra low additive phase jitter: < 0.01 ps (typ) (differential 156.25MHz, 12KHz to 20MHz integration range) Applications Low skew between outputs Networking systems including switches and routers Low delay from input to output High frequency backplane based computing and telecom platforms Separate Input output supply voltage for level shifting 2.5V / 3.3V power supply Industrial temperature support TQFP-48 package Block Diagram Pin Configuration (48-Pin TQFP) VDD VDDO 48 47 46 45 44 43 42 41 40 39 38 37 1 V 36 DDO REF IN+ 2 35 Q11+ VDDO 3 34 Q11- Q0- 4 33 Q10+ Q0+ Q 0:15 + REF IN+ 5 32 Q10- Q1- REF IN- Q 0:15 - 16 6 31 V Q1+ EE 7 30 Q9+ V EE Q9- 8 29 Q2- 9 Q8+ 28 Q2+ 10 Q8- 27 Q3- 11 26 V DDO Q3+ 12 25 V DD VDDO 13 14 15 16 17 18 19 20 21 22 23 24 GND www.diodes.com June 2018 PI6C5912016-01 1 Diodes Incorporated Document Number DS40081 Rev 1-2 V VDD DDO V Q12- DDO Q7+ Q12+ Q7- Q13- Q13+ Q6+ V Q6- EE Q14- V EE Q14+ Q5+ Q15- Q5- Q15+ Q4+ Q4- VDDO V REF IN- DDOA product Line of Diodes Incorporated PI6C5912016-01 Pin Description Pin Pin Name Type Description 1, 11, 14, 24, 25, 35, 38, 48 V Power Output power supply DDO 2, 3 Q11+, Q11- Output LVPECL output pair 11. 4, 5 Q10+, Q10- Output LVPECL output pair 10. 6, 19, 30, 43 V Power Negative power supply EE 7, 8 Q9+, Q9- Output LVPECL output pair 9. 9, 10 Q8+, Q8- Output LVPECL output pair 8. 12, 13 VDD Power Core power supply 15, 16 Q7+, Q7- Output LVPECL output pair 7. 17, 18 Q6+, Q6- Output LVPECL output pair 6. 20, 21 Q5+, Q5- Output LVPECL output pair 5. 22, 23 Q4+, Q4- Output LVPECL output pair 4. 26, 27 Q3+, Q3- Output LVPECL output pair 3. 28, 29 Q2+, Q2- Output LVPECL output pair 2. 31, 32 Q1+, Q1- Output LVPECL output pair 1. 33, 34 Q0+, Q0- Output LVPECL output pair 0.
