REFCLK
±
Reference Clock Input (Differential PECL Input): This is a clock derived from an oscillator or other
sufficiently accurate frequency source. The frequency provided at this input determines, along with
the programming, the output frequency at REFOUT
±. Micrel recommends using a 27.000MHz
frequency source.
6
PROGCS
Program Interface Chip Select (TTL Input): This signal forms part of the MicroWire interface. When
active high, this signal permits the acquisition of serial data. A falling edge on this input causes
SY87739L to re-acquire lock to a new frequency, based on the program downloaded to it.
