SP5511
Bidirectional I
2
C Bus 4-Address Synthesiser
DS3090 - 4.0 January 1997
The SP5511 is a single-chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I
2
C BUS format. In 18-lead plastic DIL package, the SP5511
has three addressable current-limited output ports (P0-P3) and
four bi-directional output ports (P0-P2) and four addressable
bi-directional open-collector ports (P4-P7) of which P6 is also
a 3-bit 5-level ADC input. The information on these ports can
be read via the I
2
C BUS. The SP5511S is a variant in a 16-lead
miniature plastic package, without P0-P2 but functionally
identical in other respects to the SP5511.
The device has four programmable I
2
C BUS addresses,
allowing two or more synthesisers to be used in a system.
