NBSG72A: 2 x 2 Crosspoint Switch, SiGe Differential, 2.5 V / 3.3 V, with Ouput Level Select
The NBSG72A is a high-bandwidth fully differential 2 X 2 crosspoint switch with Output Level Select (OLS) capabilities. This is a part of the GigaComm family of high performance Silicon Germanium products. The device is housed in a low profile 3 X 3 mm 16-pin QFN package.Differential inputs incorporate internal 50 Ω termination resistors and accept NECL (Negative ECL), PECL (Positive ECL), LVCMOS/LVTTL, CML, or LVDS. The OLS input is used to program the peak-to-peak output amplitude between 0 and 800 mV in five discrete steps. The SELECT inputs are single-ended and can be driven with either LVECL or LVCMOS/LVTTL input levels.
Features- Maximum Input Clock Frequency > 7 GHz Typical
- Maximum Input Data Rate > 7 Gb/s Typical
- 200 ps Typical Propagation Delay (OLS = FLOAT)
- 55/45 ps Typical Rise/Fall Times (OLS = FLOAT)
- Selectable Swing PECL Output with Operating Range: VCC = 2.375 V to 3.465 V with VEE = 0 V
- Selectable Swing NECL Output with NECL Inputs with Operating Range: VCC = 0 V with VEE = −2.375 V to −3.465 V
- Selectable Output Levels (0 mV, 200 mV, 400 mV, 600 mV or 800 mV Peak-to-Peak Output)
- 50 Ω Internal Input Termination Resistors
- Single−ended LVECL or LVCMOS/LVTTL Select Inputs (SELA, SELB)
- Failure management system to automatically re-route data
|
Applications- Interfacing between standard SDH equipment and DWDM equipment to select which lambda (wavelength) to be transmitted.
- Routing reference clocks to SERDES/Framers to support Metro Applications using MULTI-RATE devices
- Telecom/Datacom switching
- Serial digital video routing
- Fanout Buffering
- Automatic protection switching
