Description

The SP5026 is a programming variant of the SP5510,

allowing the design of one tuner with either 1

3-wire bus format depending on which device is

inserted. The SP5026, when used with a TV varicap

tuner, forms a complete phase locked loop tuning

system. The circuit consists of a divider-by-8 prescaler

with its own preamplifier and at 5-bit programmable

divider controlled by a serially-loaded data register.

Four

programmable, are included. The device has two

modes of operation, selected by the “mode select”

input. In mode 1, the comparison frequency is

7.8125kHz and the programmable divider MSB is

bypassed;

3.90625kHz. The comparison frequencies are both

obtained from a 4MHz crystal controlled on-chip

oscillator.
