The TDA18219HN/C1,557 from NXP Semiconductors is a versatile silicon tuner IC for terrestrial and cable digital TV reception. It fully supports digital TV standards including DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C, delivering a Low IF (LIF) signal to a channel demodulator.
Key features include integrated IF selectivity, eliminating the need for external SAW filters, and fully integrated oscillators. The device operates from a single 3.3V supply, offering low power consumption and an integrated wideband gain control. It boasts a fast 5 ms tuning time and an I2C-bus interface compatible with 3.3V microcontrollers, facilitating easy programming and on-board integration.
The tuner operates across an RF frequency range of 42 to 870 MHz, with channel bandwidths of 1.7, 6, 7, 8, and 10 MHz. The LIF channel center frequency output ranges from 3 MHz to 5 MHz. The IC is housed in a 40-HVQFN (6x6) package, suitable for surface mount applications.
This tuner facilitates design-ins by drastically reducing the size of the tuner function and providing flexibility in system solution development. It is designed for applications requiring efficient and compact digital TV reception.
