PECL Inputs
The serial data and clock PECL inputs (SD+, SD-,
SCLK+, SCLK-) require 50
termination to (V
CC
- 2V)
when interfacing with a PECL source (see Alternative
PECL Input Termination.
__________Applic ations Information
Alternative PECL Input T ermination
Figure 4 shows alternative PECL input-termination
methods. Use Thevenin-equivalent termination when a
(V
CC
- 2V) termination voltage is not available. If AC
coupling is necessary, such as when interfacing with
an ECL-output device, use the ECL AC-coupling termi-
nation.
Layout T ec hniques
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 MAX3680 data inputs.
