Pin Function
Differential Inputs: These input pairs are the differential signal inputs to the device.
They accept differential signals as small as 100mV (200mV
internally terminates with 50Ω to the VT pin.
Input Termination Center-Tap: Each side of the differential input pair terminates to a
VT pin. This pin provides a center-tap to a termination network for maximum
interface flexibility. An internal high impedance resistor divider biases VT to allow
input AC-coupling. For AC-coupling, bypass VT with a 0.1µF low ESR capacitor to
VCC. See “Interface Applications” subsection and Figure 2a.
These single-ended TTL/CMOS-compatible inputs select the inputs to the
crosspoint switch. Note that each of these inputs is internally connected to a 25kΩ
pull-up resistor and will default to a logic HIGH state if left open.
Positive Power Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as close to
the V
Output Supply: Bypass with 0.1µF//0.01µF low ESR capacitors as close to the V
pins as possible. Supplies the output buffer.
Ground: Exposed pad must be connected to a ground plane that is the same
potential as the ground pin.
CML Differential Output Pairs: Differential buffered copy of the selected input signal.
The output swing is typically 390mV. See “Interface Applications” subsection for
termination information. Output pairs Q0 to Q3 belong to Bank 1. Q4 and Q5 belong
to Bank 2.
