• Manufacturer Part Number: zl10036
• Description: Digital Satellite Tuner With Rf Bypass
• Manufacturer: Zarlink Semiconductor

2.3
The ZL10036 provides an independent bypass function, which can be used for driving a second receiver module.
The electrical characteristics of the RF input are unchanged by the state of the RF bypass.
The bypass provides a differential buffered output from the input signal with a nominal 3.5 dB gain. The unused
output should be terminated as in Figure 2 on page 2.
The bypass function is enabled by a single register bit and is not disabled by either the PD bit or the SLEEP pin.
When disabled the bypass function is in a ‘power-down’ state. On power up the bypass function is enabled.
