Note:
Associated pairs of power and ground pins need to be decoupled using 0.1
μ
F capacitors.
Note:
The PS2500 is supplied in an exposed pad 28-pin TSSOP package (EP-TSSOP). The exposed
pad is located on the bottom side of the package, and must be connected to ground for proper operation.
The exposed pad should be soldered directly to the circuit board.
CP
out_aux
Pin 20
Analog Output
Auxiliary charge pump output. The gain of the auxiliary
charge pump phase detector can be controlled from the
General Synthesizer Registers.
LD/PS
aux
Pin 18
Analog Output
Programmable output pin. Indicates auxiliary phase detector
out-of-lock as an active low pulsing open collector output (high
impedance when lock is detected), or assists the loop filter in
steering the auxiliary VCO.
This pin is configured from the General Synthesizer Registers.
