NXP Semiconductors TDA8735
The TDA8735 is a single-chip PLL synthesizer designed for satellite receivers. The device can be set to two different addresses which can be used in applications where independently tuned VCOs are required. The charge pump current can be set to 2 values with a ratio of 1 : 100 via the I2C-bus.| Part No. | TDA8735 |

GENERAL DESCRIPTION
TDA8735 To adapt to different frequency accuracy, 3 reference frequencies are selectable via the I2C-bus. A programmable switch (open-collector) is integrated to enable mode or normal switching, or other types of application.
