Note 10) The PD output is placed in the "Source" status when the phase of local oscillator division output is behind the phase comparison frequency. It is placed in the "Sink" status when the phase of local oscillator division output advances.

11) " " means high impedance status.

12) When the phase difference that is 8 times or less* of the OSC frequency continues 15 or more cycles of comparison frequency (Fref), LOCK output is placed in the "L" status. (*625ns when a 12.8MHz oscillator is used)

13) When the power supply of each system is turned off, the LOCK output status goes to "H".

14) The LOCK output circuit is an open drain output of the N channel MOS transistor. Use this circuit with pull-up.

Cautions for Handling Application Board

• For the achievement of high performances in the MIX system, the 50ohm-matching is necessary in the MIXIN port.

• Please place external elements connected to the RF line, near the pins. (Especially, resisters of TXOUT, TXE, and RXE)

• The VCC/TXVCC/RXVCC decoupling capacitances are important for the achievement of high performances. Please place these elements near the pins.

• In this diagram, coefficients of the X'tal oscillation circuit are merely examples. Please ask X'tal unit vendor about the best values of customer's specification.

Cautions for Handling

• For the achievement of high performances, fine structure elements are used in this IC. To prevent surge voltage from being applied to the IC due to static electricity, take great care for handling.

• For system not to be used, set PLL to off by transferring data.
