NBSG72A
2.5 V/3.3 V SiGe Differential
2 x 2 Crosspoint Switch
with Output Level Select
The NBSG72A is a high-bandwidth fully differential 2 × 2
crosspoint switch with Output Level Select (OLS) capabilities. This is
a part of the GigaCommt family of high performance Silicon
Germanium products. The device is housed in a low profile 3 × 3 mm
16-pin QFN package.
Differential inputs incorporate internal 50 W 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 mV 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:

• Selectable Swing NECL Output with NECL Inputs with
Operating Range: V
CC
= 0 V with V
EE
= −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 W Internal Input Termination Resistors
• Single-Ended LVECL or LVCMOS/LVTTL Select Inputs
(SELA, SELB)
