2 / 16 page 1998 Oct 23 2 Philips Semiconductors Product specification PLL frequency synthesizer TDA8735 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 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. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP.
