Crystal Requirements

Only fundamental mode crystals are supported. The default crystal frequency used is 16 MHz.

Supply Voltage Ramp-Up Rules

This chip is designed to support arbitrary power-up sequence for the three power supplies as illustrated in Figure 2. The three supplies can be power-up in arbitrary order. The only requirement is to keep RESET_N low during the power-up. The RESET_N signal can be released after all voltage supplies have been stable for at least 10μs. (T1≥ 10μs)

is 10us.

Operating Modes(See Appendix 5)

Upon reset On-chip digital regulator is on Xtal oscillator and clock out are on I2C is active

Register value at default

RF section is inactive

Loop-Through not included

I2C control On-chip digital regulator is on Xtal oscillator and clock out are on I2C is active

Register value same as previous RF section is inactive

Loop-Through not included

I2C control Tuner fully operational in digital terrestrial mode

Loop-Through not included

Note: Loop-Through can be ON or OFF for all operation modes. When Loop-Through is ON,

Packaging

QFN24 package dimensions: 4x4x0.85 mm3. Thermal resistance (Junction to ambient) is 43 o C/W.

5. Operating Modes Control

MxL603 supports 3 operating modes. (Sleep, Standby, Active) After reset signal is asserted, MxL603 will be in sleep mode. All the registers will be in default value. After certain tuning sequence (channel frequency, BW, IF etc.), MxL603 will operate in active mode. In order to save power while not in use, users can program MxL603 into standby mode; in this mode, all the registers will be stored from active mode and unnecessary blocks will be shut off. During the switch of active and standby mode, clock output will have no disturbance and GPO status will remain the same.
