INTEGRATED CIRCUITS DATA SHEET TDA8735 PLL frequency synthesizer Product specification Supersedes data of September 1994 File under Integrated Circuits, IC01 1998 Oct 23 Philips Semiconductors Product specification PLL frequency synthesizer FEATURES Complete 30 MHz single-chip tuning system Loop amplifier included 2-level current amplifier (charge pump) for adjusting the loop gain A powerful digital memory phase detector Programmable reference frequencies of 1 kHz, 10 kHz or 25 kHz I2C-bus interface Programmable address select input Software controlled switch output. APPLICATIONS Satellite sound receiver Radio receiver: LW, MW and SW. GENERAL DESCRIPTION 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. To adapt to different frequency accuracy, 3 reference frequencies are selectable via the I2C-bus. The charge pump current can be set to 2 values with a ratio of 1 : 100 via the I2C-bus. A programmable switch (open-collector) is integrated to enable mode or normal switching, or other types of application.
