Internal Equivalent Circuit

Power Down2

0 or VCC

−

Stand-by mode control pin of

reference block.

REFout1

−−

Output pin of reference frequency.

The frequency from pin 19 can be

taken out as 3 VP-P swing.

REFin2

−

2.45

Input pin of reference frequency.

This pin should be grounded

through capacitor.

REFin1

−

2.45

Input pin of reference frequency.

This pin can use as an input pin

of reference frequency buffer.

This pin should be equipped with

external 16.368 MHz oscillator

(example: TCXO).

VCC(REF Block)

2.7 to 3.3

−

Supply voltage pin of reference

block.

This pin should be externally

equipped with bypass capacitor to

minimize ground impedance.

GND(REF Block)

−

Ground pin of reference block.

2ndIFout

−

1.80

Output pin of 2nd IF amplifier.

This pin output 4.092 MHz.

This pin should be equipped with

external buffer amplifier to adjust

level to next stage on user’s

system.

VCC(2nd IF-AMP)

2.7 to 3.3

−

Supply voltage pin of 2nd IF

amplifier.

This pin should be externally

equipped with bypass capacitor to

minimize ground impedance.

2ndIFbypass

−

2.10

Bypass pin of 2nd IF amplifier.

This pin should be grounded

through capacitor.

2ndIFin2

−

2.10

Pin of 2nd IF amplifier input 2.

This pin should be grounded

through capacitor.

2ndIFin1

−

2.10

Pin of 2nd IF amplifier input 1.

2nd IF filter can be inserted

between 26 and 28.

GND(2nd IF-AMP)

−

Ground pin of 2nd IF amplifier.
