Description

The MAX2136A is a low-power global automotive TV tuner. It directly converts a variety of

broadcast signals including 3-13 segment ISDB-T, 6/7/8MHz DVB-T/T2, T-DMB/DAB, CTTB,

CMMB, and ATSC/ATSC-MH to a low-IF using a broadband I/Q downconverter. The operating

frequency range covers the VHF and UHF broadcast TV bands from 44MHz to 891MHz.

The MAX2136A integrates LNAs, RF variable-gain amplifiers (VGAs), VHF and UHF tracking

filters, I/Q downconverting mixers, baseband VGAs, and baseband filters. The VGAs typically

provide in excess of 120dB of control range. The device also includes fully monolithic VCOs and

tank circuits, as well as a complete frequency synthesizer with an on-chip crystal oscillator and

output buffer/divider.

The device incorporates a 2-wire (I²C) serial control interface with multiple read and write

addresses.

A low-power standby mode is available whereupon the signal path is shut down while leaving

the serial control interface and crystal oscillator circuits active. For further power savings, the

crystal oscillator can be disabled by placing the device in shutdown mode using the external

shutdown pin.

The MAX2136A is available in a 32-pin TQFN package (5mm x 5mm) with an exposed pad.

Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
