sp5524 Zarlink Semiconductor, sp5524 Datasheet - Page 2

• Manufacturer Part Number: sp5524
• Description: Bidirectional I2c Bus Controlled Synthesiser
• Manufacturer: Zarlink Semiconductor

for TV tuning systems. Control data is entered in the standard
I
output ports (P0-P3, P6 and P7), each capable of sinking
10mA. In addition, P1 is a 3-bit 5-level ADC input. The information
on these ports can be read via the I
programmable addresses, allowing two or more synthesisers
to be used in a system.
