Preliminary specification
UV1316
CONTROL BYTE 1
CP can be set to either 0 (low current) or 1 (high current).
Charge pump settings:
CP = 1, for fast tuning
CP = 0, for moderate speed tuning with slightly better residual oscillator FM.

Notes
1. X = don’t care; P0 to P7 are output ports on the PLL device.
2. P3 must be set 0, because at this combined input/output port, the address voltage is applied.

TELEGRAM EXAMPLES (WRITE MODE)
Start - Adb - Ack - Db1 - Ack - Db2 - Ack - Cb1 - Ack - Cb2 - Ack - Stop.
Start - Adb - Ack - Cb1 - Ack - Cb2 - Ack - Db1 - Ack - Db2 - Ack - Stop.
Start - Adb - Ack - Db1 - Ack - Db2 - Ack - Cb1 - Ack - Stop.
Start - Adb - Ack - Db1 - Ack - Db2 - Ack - Stop.
Where:
Start = start condition
Adb = address byte
Db1 = divider byte 1
Db2 = divider byte 2
Cb1 = control byte 1
Cb2 = control byte 2
Stop = stop condition.
Remark: for channel selection involving band switching, and to ensure smooth tuning to the desired channel without
causing unnecessary charge pump action, it is recommended to consider the difference between wanted channel
frequency (fw) and the current channel frequency (fc):
If fw > fc, use telegram as:
Start - Adb - Ack - Db1 - Ack - Db2 - Ack - Cb1 - Ack - Cb2 - Ack - Stop.
If fw < fc, use telegram as:
Start - Adb - Ack - Cb1 - Ack - Cb2 - Ack - Db1 - Ack - Db2 - Ack - Stop.
Unnecessary charge pump action will result in very low tuning voltage (VT 0 V) which may drive the oscillator to extreme
conditions.
