FUNCTIONAL DESCRIPTION
The TSA5511 is controlled via the two-wire I
2
C-bus. For programming, there is one module address (7 bits) and the R/W
bit for selecting READ or WRITE mode.
WRITE mode : R/W = 0 (see Table
1
)
After the address transmission (first byte), data bytes can be sent to the device. Four data bytes are required to fully
program the TSA5511. The bus transceiver has an auto-increment facility which permits the programming of the
TSA5511 within one single transmission (address + 4 data bytes).
The TSA5511 can also be partially programmed on the condition that the first data byte following the address is byte 2
or byte 4. The meaning of the bits in the data bytes is given in Table 1. The first bit of the first data byte transmitted
indicates whether frequency data (first bit = 0) or charge pump and port information (first bit = 1) will follow. Until an
I
2
C-bus STOP condition is sent by the controller, additional data bytes can be entered without the need to re-address the
device. This allows a smooth frequency sweep for fine tuning or AFC purposes. At power-on the ports are set to the high
impedance state.
The 7.8125 kHz reference frequency is obtained by dividing the output of the 4 MHz crystal oscillator by 512. Because
the input of UHF/VHF signal is first divided by 8 the step size is 62.5 kHz. A 3.2 MHz crystal can offer step sizes of 50 kHz.
