Description
External VCO input.
Programmable counter test input
(switchable by a control register).
When using the VCO PECL input,
open the Pin 5 VCO TTL input.

External inverted VCO input.
When open, this pin goes to the PECL
threshold voltage (IOVcc – 1.3V).
Only the pin 3 VCOH input with VCOL
input open can be also operated but
complementary input is recommended
in order to realize stable high-speed
operation.
