TA1297AFN

The TA1297AFN is a PLL RF modulator for UHF frequency range. The multi system can easily make the lineup development.

The features of TA1297AFN are: (1)phase locked loop frequency synthesizer for RF carrier and sound subcarrier; (2)programmable of no adjustment sound subcarriers; (3)possible to use for L-SECAM; (4)programmable picture to sound ratio; (5)bus controlled test pattern signal genertor; (6)bus controlled one logic output port; (7)bus controlled power save mode; (8)controlled by I2C bus; (9)the ripple rejection of power supply voltage is improved from TA1243BF.

The following is about the maximum ratings of TA1297AFN: (1)supply voltage 5V system: 8V; (2)supply volatge 33V system: 35V; (3)power dissipation: 850mW; (4)input terminal voltage: GND-0.3V to VCC+0.3V; (5)operating temperature: -20 to 75; (6)storage temperature: -55 to 150.
