• Manufacturer Part Number: ta1384fng
• Description: Mixer/oscillator And Pll Ic For Tv/vcr Tuner
• Manufacturer: TOSHIBA Semiconductor CORPORATION

●Rsa, Rsb: Reference frequency divider ratio select bit.
●OS: tuning amplifier control bit
●B4, B3, B2, B1: Band output port control and band change control bit
●POR: power-on reset flag
●FL: lock detect flag
●X : don’t care
-EXAMPLE OF BUS DATA TRANSMITTER-
S: Start
ADR: Address Byte
DIV1: Divider Byte 1 (frequency data)
DIV2: Divider Byte 2 (frequency data)
CONT: Control Byte
BAND: Bandswitch Byte
A: Acknowledge
P: Stop
[1] Transmitter - 1
[2] Transmitter - 2
[3] Transmitter – 3 (This can be applied if control data and bandswitch data have already been programmed.)
[4] Transmitter – 4 (This can be applied if frequency data have already been programmed.)
[5] Transmitter – 5 (This can be applied if frequency counter data and bandswitch data have already been programmed.)
Until the I²C-bus STOP condition is detected, it is possible to input the additional data without transmitting the address
data again. (For example: Frequency sweep is possible with additional frequency data.)
If data transmission is aborted, data programmed before the abort are valid.

When the bandswitch data is [1] for either B1 or B2, VHF mode is effective.
When the bandswitch data is [0] for both B1 and B2, UHF mode is effective.
