Note: (1) Positive IF frequency denotes no spectral inversion, negative frequency has inverted spectrum
(2) Ratio of level through mixer between wanted input signal at 1575.42MHz and image signal at
1567.236MHz.
(3) Centered at IF CF = 4.092 MHz.
(4) The application should be designed to meet this maximum level across 1575.42 ±5 MHz. An
absence of strong interferers is assumed.
(5) 1575.42MHz signal for blocking measurement is CW at a fixed level of -101dBm.
(6) Levels do not include effects of any external RF filtering.
(7) AGC loop disabled. Receiver is deemed to have recovered when the rms signal level in the ADC
has resettled to its initial value ±1.5 dB.

FREF2 (pin 14), OSC_EN (pin 19) and RX_EN (pin 23).
(2) Applies to RX_EN (pin 23) only. Figure dominated by 1.5 M! (nom) on-chip pull-down resistor.
(3) Applies to all Logic pins used as outputs: CLK_OUT (pin 9), SIGN (pin 10), and MAG (pin 11).
(4) Output Current set at Nominal level; no Current Setting Resistor on RVI (pin 20). Positive value
indicates current source; negative value indicates current sink.
Logic Output Current Drive Adjustment Settings
The Logic Outputs on the SE4110L can be adjusted to compensate for parasitics in application board layout. This can
be achieved by adding a resistor between RVI (pin 20) and VDDQ (pin 17) as shown below.
The additional interface capacitance of PCB tracking and connectors between the SE4110L output and baseband IC
input is included in these figures.
These figures are Typical only, and are not guaranteed across temperature and silicon process.
