3, 6
IN, /IN
Differential Input: This differential input accepts AC- or DC-coupled signals as
small as 100mV (200mVPP). Each pin of this pair internally terminates to a VT pin
open. Please refer to the “Input Interface Applications” section for more details.
4
VT
Input Termination Center-Tap: Each side of the differential input pair terminates
to this VT pin. The VT pin provides a center-tap to a termination network for
maximum interface flexibility. See the
“Input Interface Applications” section for
more details.
5
VREF-AC
Reference Voltage: This output biases to VCC–1.2V (typical). It is used for AC-
coupling inputs IN and /IN. Connect VREF-AC directly to the corresponding VT
pin. Bypass with 0.01uF low ESR capacitor to VCC. Maximum sink/source
capability is 1.5mA.

100k LVPECL Differential Outputs: Differential buffered output copy of the input
signal. The LVPECL output swing is typically 800mV into 50 to VCC–2V.
Unused output pairs may be left floating with no impact on jitter. See “LVPECL
Output” section.
