TDA8735 Datasheet - NXP

TDA8735 PLL frequency synthesizer

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 vi.
