Low-Voltage Differential-Signal
Inputs and Outputs
The MAX3890 has LVDS inputs and outputs for inter-
facing with high-speed digital circuitry. The LVDS
standard is based on the IEEE 1596.3 LVDS specifi-
cation. This technology uses 250mV to 400mV differ-
ential low-voltage swings to achieve fast transition
times, minimized power dissipation, and noise immu-
nity.
For proper operation, the parallel clock LVDS outputs
(PCLKO+, PCLKO-) require 100
differential DC termi-
nation between the inverting and noninverting outputs.
Do not terminate these outputs to ground.
The parallel data and parallel clock LVDS inputs
(PDI_+, PDI_-, PCLKI+, PCLKI-, RCLK+, RCLK-) are
internally terminated with 100
differential input resis-
tance, and therefore do not require external termina-
tion.
PECL Outputs
The serial-data PECL outputs (SDO+, SDO-, SCLKO+,
SCLKO-) require 50
DC termination to (VCC - 2V) (see
the Alternative PECL-Output Termination section).
Current-Mode Logic Outputs
The system loopback outputs (SLBO+, SLBO-) of the
MAX3890 are designed using CML. The configuration
of the MAX3890 current-mode logic (CML) output cir-
cuit includes internal 50
back termination to VCC
(Figure 3). These outputs are intended to drive a 50
transmission line terminated with a matched load
impedance.
