APPLICATION INFORMATION
The MC10/100EP446 is an integrated 8:1 parallel to serial
converter. An attribute for EP446 is that the parallel inputs
D0–D7 (Pins 17 – 24) can be configured to accept either
CMOS, ECL, or TTL level signals by a combination of
interconnects between VEF (Pin 27) and VCF (Pin 26) pins.
For CMOS input levels, leave VEF and VCF open. For ECL
operation, short VCF and VEF (Pins 26 and 27). For TTL
operation, connect a 1.5 V supply reference to VCF and leave
the VEF pin open. The 1.5 V reference voltage to VCF pin can
be accomplished by placing a 1.5 k
W or 500 W between VCF
and VEE for 3.3 V or 5.0 V power supplies, respectively.
Note: all pins requiring ECL voltage inputs must have a
50
W terminating resistor to VTT (VTT = VCC – 2.0 V).
The CKSEL input (Pin 2) is provided to enable the user to
select the serial data rate output between internal clock data
rate or twice the internal clock data rate. For CKSEL LOW
operation, the time from when the parallel data is latched
to when the data is seen on the SOUT is on the falling edge
of the 7th clock cycle plus internal propagation delay
(Figure 7). Note the PCLK switches on the falling edge of
CLK.
