OPERATIONS
1. Serial data input
Serial data can control 4 group functions separately.
Data is always input from LSB and final 2bit data selects the group.
0 Group 1 I Reference divider frequency division ratio.
Phase comparator S, R inputs replace.
0 Group 2 - Programmable counter frequency division ratio.
0 Group 3 - Wide purposive output ports.
0 Group 4 -ll Phase comparator D02 output ON/OFF control.
Lock detector compulsory set.
Serial data is composed of 3 lines of DATA, CK and STB.
DATA is input orderly in internal shift register at going rising edge of CK.
By setting STB "H" level after all DATA is input, DATA is transferred to the latch selected by the
group code and this LSI can be controlled.
Serial data input 3 terminals build in schmitt trigger circuits that protect from data error by noise.
Concerning the data status of each group, refer to the respective block explanations.

0 Crystal oscillation amp allows crystal oscillation up to 15MHz and inputting signal in XT terminal
externally up to 15MHz through a coupling capacitor.
It Programmable divider is composed of binary 12bit.
Voluntary frequency division of range 5--4095 division is possible by serial data given externally.
So a crystal to generate reference frequency can be selected freely and common use of the
crystal using other purpose is possible.
By setting Latch-1 (L1) at "H" level, frequency division ratio is fixed at 1024 division neglecting
serial data.
And at this time serial data becomes brief.
0 Latch-2 (L2) is a control latch to replace reference divider output and programmable counter
output before inputting to phase comparator circuit.
Set L2 at "L" level when external low pass filter is an inversion type, and set "H" level when
not an inversion type.
It Serial data
Serial data to control reference divider block is of 16bit as following construction.

4. Phase comparator
Phase comparator converts phase difference of reference divider output and programmable counter
output into VCO control voltage and has features as following.
It Always operating ordinary tri-state output (D01).
It Tri-state output (D02) which can be controlled ON/OFF according to serial data given externally.
0 Phase comparator outputs (H, L) to connect high voltage charge pump externally.
0 Lock detector output (LD) which can be compulsorily set by data given externally.
(1) Example use of D01, D02 terminal
- C R3
COMPARATOR VCO
When change a channel, ON the D02 output and make the time constant of the low pass
filter smaller to make PLL lock state fastly.
And after PLL is locked, OFF the D02 output and make the time constant larger to
improve side-band spurious feature and stability.

TOSHIBA TC9181P/F
Example use of H, L terminals B<12V
When connect an external passive low pass filter,
supply voltage of charge pump should be high.
In this case connect an external PNP transistor as a vco
right figure.
0 Lock detector j
Lock detector (LD) outputs pulse signal during phase deference time detected by phase
detector circuit.
Additionally this lock detector output can be fixed unlocked state compulsorily by serial
data given externally.
By fixing LD unlocked state just before channel changing to stop transmission output
and canceling unlocked state after a definite time from the channel changing, troubles
at channel changing e.g., overshoot can be prevented from.
