1FEATURES DESCRIPTIONThe
250 Mbps– 2.5 Gbps Low Jitter Operation CML
• Optional Fixed Input Equalization backplane
Selectable Output De-Emphasis down
applications requiring both low and high frequency
• Individual Loopback Controls data rates. Each input stage hasa fixed equalizerto
• On-Chip Termination reduce ISI distortion from board traces. The
• +3.3V Supply equalizers are enabled through two control pins.
These control pins provide flexibilityin applications
• Lead-Less WQFN-60 Pin Package where ISI distortion may vary from one directionto
– (9 mmx9 mm x0.8 mm, 0.5 mm Pitch) another. All output drivers have four selectable steps
• −40°Cto +85°C Industrial Temperature Range of de-emphasisto compensate for transmission loss.
The de-emphasis blocks are also groupedin fours.In
• 6 kV ESD Rating, HBMaddition, the DS25BR400 also has loopback control
capability on four channels. All the CML drivers have
APPLICATIONS 50Ω terminationto VCC. All receivers are internally
• Backplaneor Cable Driver terminated with differential 100Ω.
