7 / 24 page 1996 Jun 18 7 Philips Semiconductors Product specification Front-end and PLL synthesizers for car radios TEA6810V; TEA6811V I2C-BUS ORGANIZATION The TEA6810V; TEA6811V is controlled via the I2C-bus which is driven from the TEA6821V. For programming purposes a module address and four data bytes are required. When used partially, the transmission must be ended by a stop condition. Table 1 Bit organization Table 2 I2C-bus address and received bytes Notes 1. N1 divider ratio is (N + 2); where N is the programmed binary number composed of bytes 1 and 2. For the minimum ratio; if N < 2048 then N1 divider ratio is {2048 + (N − 2)}. 2. X = don’t care.
