TDA6650ATT; TDA6651ATT
5 V mixer/oscillator and low noise PLL synthesizer
[1]
Important recommendation: to obtain the performances mentioned in this specication, the serial resistance of the crystal used with this
oscillator must never exceed 120
. The crystal oscillator is guaranteed to operate at any supply voltage between 4.5 V and 5.5 V and
at any temperature between
20 °C and Tamb(max), as dened in Section 10.
[2]
The drive level is expected with a 50
series resistance of the crystal at series resonance. The drive level will be different with other
series resistance values.
[3]
The VXTOUT level is measured when the pin XTOUT is loaded with 5 k in parallel with 10 pF.

Characteristics …continued
VCCA =VCCD =5V; Tamb =25 °C; values are given for an asymmetrical IF output loaded with a 75 load or with a
symmetrical IF output loaded with 1.25 k
; positive currents are entering the IC and negative currents are going out of the IC;
the performances of the circuits are measured in the measurement circuits Figure 27 and 28 for digital application or in the
measurement circuits Figure 29 and 30 for hybrid application; unless otherwise specied.
