The MAX2164 includes a stand-alone LNA with 1.2dB (typical) noise figure, eliminating the need for an external LNA. The MAX2164 also includes RF variable-gain amplifiers, I and Q downconverting mixers, a baseband variable-gain amplifier, and a low-IF filter. The MAX2164 has monolithic VCOs, a complete frequency synthesizer, and an on-chip crystal oscillator with output buffer. The device operates with a crystal from 32MHz to 36MHz.
The MAX2164 features a 2-wire I2C-compatible serial control interface with multiple addresses for multituner applications. A low-power standby mode is available that shuts down the signal path leaving the control interface, crystal oscillator, and buffer circuits active. An external pin can shut down the entire device.
The MAX2164 is specified for operation in the extended -40°C to +85°C temperature range and is available in a 2.06mm x 2.49mm x 0.35mm, 5 x 6 bump, lead-free WLP package.
