Description
Connect a external loop filter
capacitor.
Typically 0.33µF.
Ground for PLL circuits.
No connect
Ground for PLL circuits.
Both VEEP1 and VEEP2 must be
grounded.
Connect to VEEP1 through a
external resistor to determine
VCO frequency.
Typically 2.4kΩ.

Lock detector (TTL).
Driven low, while synchronization
is lost.
If SQLCH is asserted(low),fixed
high even when lock is lost.
