MITEL SP5512KGMPAS Datasheet

The SP5512 is a single-chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I2C 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 I2C BUS.

The device has one fixed I2C BUS address and three
programmable addresses, allowing two or more synthesisers
to be used in a system.

NOTES

1. Source impedance between all output ports and ground is approximately 5Ω . This should be taken into account when calculating output port
saturation voltages.

2. The recommended crystal series resistance quoted refers to all conditions including start-up.
