SP5510

1.3GHz Bidirectional I2C BUS Controlled Synthesiser

Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0 DS2184 - 4.0 Janaury 1997

The SP5510 is a single-chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I2C BUS format. The device has four addressable current­limited output ports (P0-P3) and four bi-directional open­collector ports (P4-P7), one of which (P6) is also a 3-bit 5-level
ADC input. The information on these ports can be read via the
I2C BUS. The SP5510S is a variant in a 16-lead miniature
plastic package, without P0-P2 but functionally identical in
other respects.

Both variants have one fixed I2C BUS address and three
programmable addresses, allowing two or more synthesisers
to be used in a system.
