Pin Function
Differential Inputs: These input pairs are the differential signal inputs to the device. These inputs
accept AC- or DC-coupled signals as small as 200mV. Each pin of a pair internally terminates to
a VT pin through 50Ω. Please refer to the “Input Interface Applications” section for more details.
Input Termination Center-Tap: Each side of the differential input pair terminates to a VT pin. The
VT0 and VT1 pins provide a center-tap to a termination network for maximum interface flexibility.
See the “Input Interface Applications” section for more details.
This single-ended TTL/CMOS-compatible input selects the inputs to the multiplexer. This input
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
possible.
Differential Outputs: These LVPECL output pairs are the outputs of the device. They are a logic
function of the IN0, IN1, and SEL inputs. Please refer to the truth table for details. Unused
output pairs may be left open.
Ground. Ground and exposed pad to be tied together to most negative potential of chip.
Power-On Reset (POR) Initialization Capacitor. When using the multiplexer with RPE capability,
this pin is tied to a capacitor to V
a known state. If this pin is tied to V
function as a normal multiplexer. See “Application” section for more details. The CAP pin should
never be left open.
Reference Voltage: These outputs bias to V
(IN,/IN). Connect VREF_AC directly to the VT pin. Bypass with 0.01µF low ESR capacitor to
VCC. See "Input Interface Applications" section. Maximum sink/source current is ±1.5mA.
