GENERAL DESCRIPTION
The ADCLK846 is a 1.2 GHz/250 MHz, LVDS/CMOS, fanout
buffer optimized for low jitter and low power operation. Possible
configurations range from 6 LVDS to 12 CMOS outputs,
including combinations of LVDS and CMOS outputs. Two
control lines are used to determine whether fixed blocks of
outputs are LVDS or CMOS outputs.
The clock input accepts various types of single-ended and
differential logic levels including LVPECL, LVDS, HSTL, CML,
and CMOS.
Table 8 provides interface options for each type of connection.
The SLEEP pin enables a sleep mode to power down the device.
This device is available in a 24-pin LFCSP package. It is specified
for operation over the standard industrial temperature range of
40°C to +85°C.
