MAX3885
DC termination between the inverting and noninverting
outputs for proper operation. Do not terminate these
outputs to ground. The synchronization LVDS inputs
(SYNC+, SYNC-) are internally terminated with 100
Ω
differential input resistance and, therefore, do not
require external termination.
PECL Inputs
Because of the self-biasing resistor networks, the serial
data and clock PECL inputs (SD+, SD-, SCLK+, SCLK-)
require 53
Ω termination to VCC - 2V when interfacing
with a PECL source (see
Alternative PECL Input
Termination). This results in an equivalent input resis-
tance of 50
Ω.
Applications Information
Alternative PECL Input Termination
Figure 5 shows alternative PECL input-termination
methods. Use Thevenin-equivalent termination when a
VCC - 2V termination voltage is not available. When
interfacing with an ECL-output device, the MAX3885’s
internal self-biasing allows easy ECL AC-coupling ter-
mination.
Layout Techniques
For best performance, use good high-frequency layout
techniques. Filter voltage supplies and keep ground
connections short. Use multiple vias where possible.
Also, use controlled impedance transmission lines to
interface with the MAX3885 high-speed inputs and out-
puts.
