SP5512
1.3GHz Bidirectional I
2
C BUS Controlled Synthesiser
Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0
DS2384 - 4.0 January 1997
The SP5512 is a single-chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I
2
C BUS format. The device has six controllable open-collector
output ports (P2-P7), each capable of sinking 20mA. In addition,
P6 is a 3-bit 5-level ADC input. The information on these ports
can be read via the I
2
C BUS.
The device has one fixed I
2
C BUS address and three
programmable addresses, allowing two or more synthesisers
to be used in a system.
