I²C-bus mode enables two-way bus communications with Write Mode, which receives data, and Read Mode, which sends data. Write Mode and Read Mode are set using the last bit (R/W bit) of the address byte. If the last address bit is set to [0], Write Mode is selected; if it is set to [1], Read Mode is selected. Addresses can be set using the hardware bits, and four programmable addresses are available. With this setting, multiple frequency synthesizers can be used in the same I²C-bus. The address for the hardware bit setting can be selected by applying voltage to the address setting pin (ADR: pin 3).An address is selected according to the set bits. If the correct address bytes are received, the serial data (SDA) line is “Low” during acknowledgment; when Write Mode is set, the serial data (SDA) line is “Low” during the next acknowledgment if the data byte is programmed. The IC is equipped with 1/2 and 1/4 built-in prescalers, and it is possible to change from one prescaler to the other using input data. When a frequency step of 62.5 kHz is selected, the 1/2 prescaler operates with a divider ratio of 1024 to 4095, and the 1/4 prescaler operates with a divider ratio of 4096 to 32767. When the frequency step selected is 31.25 kHz and 50 kHz, the 1/2 prescaler operates with a divider ratio of 1024 to 8191, and the 1/4 prescaler operates with a divider ratio of 8192 to 32767. In addition, even if the prescaler is changed, the data is calculated in the internal circuit and is processed so that the comparison frequency in each the frequency step does not change. For a frequency step of 62.5 kHz: 15.625 kHz comparison frequency For a frequency step of 50 kHz: 12.5 kHz comparison frequency For a frequency step of 31.25 kHz: 7.8125 kHz comparison frequency This IC incorporates a built-in power-on reset circuit for which a detection voltage of approximately 1.4 V has been set. When the Vcc is supplied, a delay or stoppage in a power supply voltage close to this detection voltage may cause the power-on reset circuit to malfunction, in which case there is a risk that some data may not be received even after the recommended voltage has been restored. A) Write Mode (Setting Command) When WRITE mode is set so that the different types of information may be received, byte 1 is used to specify the address data; byte 2 and byte 3, the frequency data; byte 4, function setting data such as the divider ratio setting; and byte 5, the output port data (bandswitch data). Data are latched and transferred one after the other in the case of byte 3, byte 4 and byte 5, while byte 2 and byte 3 are latched and transferred as a two-byte set (byte 2 + byte 3). Once a correct address is received and acknowledged, the data type is determined by whether the first bit of the next byte is set to [0] or [1]. [0] indicates frequency data, while [1] indicates function setting or output data. Until the I²C-bus STOP CONDITION is detected, the additional data can be input 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. BYTE 1 Hardware bit setting of byte 1 is possible using the address data. The hardware bit is set with the voltage applied to the address-setting pin (ADR: pin 3). BYTE 2, BYTE 3 Byte 2 , byte 3 are stored in the 15-bit shift register with counter data for the frequency setting, and control the 15-bit programmable counter ratio. The program frequency can be calculated in the following formula: fosc = 4 x fr x N. fosc 4 fr N : Program frequency : Prescaler : Phase comparator reference frequency (step frequency) : Counter total divider ratio fr is calculated using the crystal oscillator and the reference frequency divider ratio set in byte 4 (control byte): fr = crystal oscillator frequency / reference divider ratio. The reference frequency divider ratio can be set to 1/512, 1/320, and 1/256. When using a 4-MHz crystal oscillator, fr = 7.8125 kHz, 12.5 kHz, and 15.625 kHz. The step frequency is 31.25 kHz, 50.0 kHz, and 62.5 kHz. 11 2004/11/24 TA1384FNG BYTE 4 Byte 4 is a control byte used to set the different functions. Bit 2 (CP) and controls the output current of the charge-pump circuit. When bit 2 is set to [0], the output current is set to +55 µA; when it is set to [1] , it is +250 µA. Bit 3 (T2), bit 4 (T1), and bit 5 (T0) are used to set the phase comparator reference signal output and counter divider output in test mode. (For details of test mode, see the test mode setting table.) Bit 6 (Rsa) and bit 7 (Rsb) are used to set the crystal reference frequency divider ratio. (For details of the crystal reference frequency divider ratio, see the table for crystal reference frequency divider ratios.) Bit 8 (OS) is used to set the charge-pump driver amplifier output setting. When bit 8 is set to [0], the output is ON (the normal setting used); when it is set to [1], the output is OFF (charge pump is sink mode). BYTE 5 Byte 5 is used to set the test mode and control the output ports (Band 1 ~ Band 4). When an output port is set to [0], it is OFF; when it is set to [1], it is ON. Bandswitch setting is also used to switch between the VHF and UHF bands. ・ When the bandswitch data for either B1 or B2 is [1], VHF mode is effective. ・ When the bandswitch data for both B1 and B2 is [0], UHF mode is effective. Set the following maximum values for currents to the bandswitch driver. Ensure also that the total band current is within 17 mA when two bands are operating at the same time. ・ Band 1 (pin 4) output current: 7 mA (maximum) ・ Band 2 (pin 5) output current: 10 mA (maximum) ・ Band 3 (pin 6) output current: 3 mA (maximum) ・ Band 4 (pin 7) output current: 7 mA (maximum) B) READ MODE (Status Request) When Read Mode is set, power-on reset operation status and phase comparator lock detector output status are output to the master device. Bit 1 (POR) indicates the power-on reset operation status. When the power supply of Vcc stops, this bit is set to [1]. The conditions for reset to [0] are that voltage supplied to Vcc is 3V or higher, that transmission is requested in READ MODE, and that the status is output. (When Vcc is turned on, bit 1 is also set to [1].) Bit 2 (FL) indicates the phase comparator lock status. When this is locked, [1] is output; when it is unlocked, [0] is output. 12 2004/11/24 TA1384FNG DATA FORMAT A) WRITE MODE MSB LSB 1 Address Byte 1 1 0 0 0 MA1 MA0 R/W = 0 ACK 2 Divider Byte 1 0 N14 N13 N12 N11 N10 N9 N8 ACK 3 Divider Byte 2 N7 N6 N5 N4 N3 N2 N1 N0 ACK (L) 4 Control Byte 1 CP T2 T1 T0 Rsa Rsb OS ACK (L) 5 Band SW Byte X X X X B4 B3 B2 B1 ACK (L) X :DON’T CARE ACK :Acknowledged (L) :Latch and transfer timing B) READ MODE MSB 1 Address Byte 2 Status Byte LSB 1 1 0 0 0 MA1 MA0 R/W=1 ACK POR FL 1 1 1 1 1 1 - ACK :Acknowledged DATA SPECIFICATIONS ●MA1, MA0 : programmable hardware address bits MA1 MA0 ADDRESS PIN APPLIED VOLTAGE 0 0 0 0 1 OPEN or 0.2Vcc 1 0 0.4Vcc 1 1 to 0.1Vcc to 0.9Vcc to to 0.3Vcc 0.6Vcc Vcc ●N14 – N0 : programmable counter data ● CP : charge pump output current setting [0] : + 55 µA (typ.)

The device should not be inserted into or removed from the test apparatus while the voltage is being applied; otherwise breakdown or deterioration in performance of the device may result. Also, avoid any abrupt increasing or decreasing of the voltage. Overshoot or chattering of the power supply may cause the IC to be degraded. To avoid this problem, equip the power supply line with filters. 2. The peripheral circuits described in this datasheet are given only as system examples for evaluating the performance of the device.
