The 3-wire bus mode is equipped with an 18-bit / 19-bit automatic selection circuit. Frequency steps can be switched, depending on the voltage applied to the BUS-SW pin. The I2C bus conforms to the standard I2C bus format. The bus supports two-way bus communications control, consisting of WRITE mode where data are received and READ mode where data are transmitted. In READ mode, the voltage applied on the A / D converter input pin can be transmitted and output with 5-level resolution. (This function is only valid when the I2C bus is selected. When the 3-wire bus is selected, the A / D converter input pin function as the LOCK output pin.) Addresses can be set using the hardware bits. Three programmable addresses are supported. 3-wire bus and standard I2C bus are switches by the voltage applied on the BUS-SW pin. The power-on reset circuit is built in this product, and the detection voltage is designed about 1.4 V. If it raises to voltage of operation after making it stop for a while near the voltage of a power-on reset circuit of operation at the time of starting of a power supply, a power-on reset circuit may not operate normally.

The clock number during a high level of the enable signal must be set to 18-bit for the latch condition. (The number of clock rising edges is 18). For latch timing, the first four bits, which control the bandswitch buffers, are loaded at the fifth rising edge of the clock, and the data is updated. The programmed counter data transmits the 18-bit data, latched on the falling edge of the enable signal. During 18-bit data transmission, “N14” programmable counter data is constantly set to [0] , and the phase comparator reference frequency divider ratio is automatically set to “1 / 64”. Details of the data timing, see the data timing chart (Figure 1) l 19-bit DATA TRANSMISSION : During a high level of the enable signal, the data is clocked into the register on the falling edge of the clock. The clock number during a high level of the enable signal must be set to 19-bit for the latch condition. (The number of clock rising edge is 19). For latch timing, the first four bits, which control the bandswitch buffers, are loaded at the fifth rising edge of the clock, and the data is updated. The programmed counter data transmits the 19-bit data, latched on the falling edge of the enable signal. During 19-bit data transmission, the phase comparator reference frequency divider ratio is automatically set to “1 / 80” or “1 / 128” in BUS-SW mode. Details of the data timing, see the data timing chart (Figure 1) 2001-03-01 9/21 TD7624AFN (1) TEST MODE In the test mode, the settings can be changed and the functions can be checked. Change from the normal mode to the test mode with a 27-bit or more of clock and data transmission during a high level of the enable signal. The data are latched at the 27th falling edge of the clock signal, validating the previous 27-bit data. The latch timing is the same as normal data. The 4-bit bandswitch data are latched at the 5th bit rising edge of the clock signal, and the data is updated. The programmable counter data are latched at the 20th bit rising edge of the clock signal, and the data is updated. The test data are latched at the 27th bit falling edge of the clock signal, and the data is updated. When the mode is changed from test to normal, RSa changes depending on the data bit length (18 or 19 bits, automatic discrimination). The data set in RSb in test mode are retained (see the table below).

The I2C bus mode enables two-way bus communications with the WRITE mode, which receives data, and READ mode, which status data. WRITE 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 set ; if set to [1] READ mode is set. Address can be set using the hardware bits. Three programmable address can be programmed. With this setting, multiple frequency synthesizers can be used in the same I2C bus line. The address for the hardware bit setting can be selected by applying voltage to the address setting pin (ADR : Pin 15). An address is selected according to the set bits. When the correct address byte is received, during acknowledgment, serial data (SDA) line is “Low”. If WRITE mode is set at this time, when the data byte is programmed, the serial data (SDA) line is “Low” during the next acknowledgment. a) WRITE mode (setting command) When WRITE mode is set, Byte 1 segment the address data ; Bytes 2 and 3 segment the frequency data ; Byte 4 segment the divider ratio setting and function setting data ; and Byte 5 segment the output port data. Data are latched and transferred at the end of Byte 3, Byte 4 and Byte 5. Byte 2 and Byte 3 are latched and transferred is done with a two byte set (Byte 2 + Byte 3). Once a correct address is received and acknowledged, the data type is determined according to [0] or [1] set in the first bit of the next byte. That is, if the first bit is [0] , the data are frequency data ; if [1] , function setting or output port data. Until the I2C bus STOP CONDITION is detected, the additional data can be input without transmitting the address again. (Ex : Frequency sweep is possible with additional frequency data.) If data transmission is aborted, data programmed before the abort are valid. Byte 1 can set the hardware bit with address data. The hardware bit is set with voltage applied to the address setting pin (ADR : Pin 15). Bytes 2 and 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 = fr × N fosc : Program frequency fr : Phase comparator reference frequency (Step frequency) N : Counter total ratio fr is calculated using the crystal oscillator frequency and the reference frequency divider ratio set in byte 4 (control byte). (fr = X’tal oscillator frequency / reference frequency divider ratio) The reference frequency divider ratio can be set to 1 / 64, 1 / 128 and 1 / 80. When using a 4 MHz crystal oscillator, fr = 62.5 kHz, 31.25 kHz and 50 kHz. The step frequency are 62.5kHz, 31.25kHz, and 50kHz. Byte 4 is a control byte used to set function. Bit 2 (CP) controls the output current of the charge-pump circuit. When bit 2 is set to [0] : the output current is set to ±60 µA ; when set to [1] , ±280 µA. Bit 3 (T2), Bit 4 (T1) and Bit 5 (T0) are used to set test mode. They are used to set the phase comparator reference signal output, and counter divider output. For details of test mode, see the test mode setting table. Bit 6 (RSa) and Bit 7 (RSb) are used to set the X’tal reference frequency divider ratio. For details of the X’tal reference frequency divider ratios, see the table for X’tal reference frequency divider ratios. Bit 8 (OS) is used to set the charge-pump drive amplifier output setting. When bit 8 is set to [0] the output is ON (Normal Use) ; when set to [1] the output is OFF (Tr. Output is Low Level). Byte 5 is used to set and control the output port (Bands 1~4). When an output port set to [0] is OFF ; when set to [1] is ON. Two output ports can be operation turned on, but be sure to keep the total output current under 50mA. 2001-03-01 12/21 TD7624AFN b) READ mode (status request) When READ mode is set, power-on reset operation status, phase comparator lock detector output status, and 5-level A / D converter pin input voltage status are output to the master device. Bit 1 (POR) indicates the power-on reset operation status. When the power supply of VCC1 stops, bit 1 is set to [1] . The condition for reset to [0] , voltage supplied to VCC1 is 3 V or higher, transmission is requested in READ mode, and the status is output. (when VCC1 is turned on, bit 1 is also set to [1] .) Bit 2 (FL) indicates the phase comparator lock status. When locked, [1] is output ; when unlocked, [0] is output. Bits 6, 7 and 8 (A2, A1, A0) indicate the 5-level A / D converter status. The voltage applied to the A / D converter input pin (pin 12) is output through a 5-level resolution. For the voltage applied on the A / D converter input pin, 5-level resolution, and the output bits, see the table. (Ex : The AFT output voltage data can be given to the master device.) 2001-03-01 13/21 TD7624AFN DATA FORMAT a) WRITE MODE BYTE 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 × × × × B4 B3 B2 B1 ACK (L) × ACK (L) : : : DON’T Care Acknowledged Latch and transfer timing b) READ MODE BYTE MSB 1 Address Byte 2 Status Byte LSB 1 1 0 0 0 MA1 MA0 R/W=1 ACK POR FL 1 1 1 A2 A1 A0 ― ACK : Acknowledged DATA SPECIFICATIONS l MA1, MA0 : Programmable hardware address bits ADDRESS PIN APPLIED VOLTAGE MA1 MA0 0~0.1 VCC1 0 0 0.4 VCC1~0.6 VCC1 1 0 0~VCC1 0 1 0.9 VCC1~VCC1 1 1 l CP : Charge-pump output current setting [0] : ±60 µA (Typ.)
