The SE4150L includes two RF inputs with integrated antenna switching and external active-antenna current detection. A high-linearity onchip LNA is used with one of the inputs, allowing the SE4150L to be used in multi-function wireless systems, without the need for additional external LNA devices. A fully integrated image-reject low-IF mixer is used with a linear AGC, an on-chip IF filter, and a 2-bit analogue-todigital converter (ADC). The SE4150L features two gain control modes, to optimize the performance of the LNA and mixer for systems which either require high signal handling, or systems which need minimal supply current. The SE4150L synthesizer is fully integrated including the VCO and PLL loop-filter. The synthesizer can operate from a 16.368 MHz reference frequency, normally with an external TCXO. The SE4150L is optimized for operation from a 3.3 V core power supply. It incorporates current-controlled low-spurious output buffers which may operate from a separate external supply. Output buffers supply sufficient current to drive up to 15 pF load directly.

The antenna current detector is designed to monitor the supply current to an external active antenna and provide a logic output, ANT_DET (pin 8). This is used to indicate if the current is within an expected range. The current monitor senses the current which passes through the ANT_BIAS (pin 2) output. The LNA noise figure is the largest single contributor to overall system sensitivity in GPS signal reception. The internal LNA of the SE4150L allows excellent performance to be achieved from a low-power GPS receiver without requiring any additional active components. The GPS L1 input signal which is applied to LNA_IN (pin 4), is a spread-spectrum signal centered on 1575.42 MHz with a 1.023Mbps BPSK modulation. The signal level at the antenna is typically -130 dBm in open-sky conditions, dropping to below -150 dBm in masked signal areas (e.g. indoors). The LNA input requires a minimum of external matching components to achieve good RF gain with minimal noise figure. Although attention should be paid to track lengths and interference throughout the design, the LNA input matching circuit is the only RF circuit critically sensitive to layout. The LNA output includes internal 50Ω matching for connection to the mixer input, either directly or via an optional external filter. Antenna Switch An antenna switch is included on the SE4150L, to allow selection of either the LNA_IN (pin 4) RF path, or the ANT1_IN (pin 3) RF path to connect to a single RF output; ANT_SW_OUT (pin 7). This is useful in systems where two antenna sources can be provided (e.g. a PND, where an internal antenna and a socket for an external antenna are available). The antenna switch is driven from the antenna current detector block. The antenna switch will transfer the RF input from the default LNA_IN (pin 4) over to ANT1_IN (pin 3), when the antenna current detector block senses a current being consumed, for example, from an external active antenna. The switching threshold is typically 1mA with some hysteresis. ANT_DET (pin 8) is connected to the switchover control of the internal antenna switch. The antenna switch will transfer the route of the RF input path from the internal LNA (supplied from the LNA_IN (pin 4) input) across to ANT1_IN (pin 3), through to the ANT_SW_OUT (pin 7) output, when current is detected. ANT_BIAS (pin 2) should be connected to the core connection of a coax socket via an isolating choke for an external active antenna, in conjunction with ANT_IN (pin 3) connected to the same core connection of the socket via a dc-blocking capacitor. When an external active antenna is connected, DC current to drive the active antenna will flow through ANT_BIAS (pin 2), and the antenna current detector. Antenna Switch Override The antenna switch (and antenna current detector) can be overridden by externally driving ANT_DET (pin 8) from a low-impedance external source, at VDDN (pin 22) or GND levels. This can be useful, for example, in applications where the external antenna is not powered by the SE4150L feed, or to facilitate user override via the host processor man-machine interface. The external source applied to ANT_DET (pin 8) must be able to source >300 uA into the pin, or sink >70 uA out of the pin to allow guaranteed levels to be set. Mixer RF Input The mixer RF input, MIX_IN (pin 11), is a singleended 50 Ω input designed to interface either to ANT_SW_OUT (pin 7) or to the output of an external filter. An external active antenna can also be Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 202445A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • September 25, 2012 5 DATA SHEET SE4150L: GPS Receiver IC Preliminary Datasheet connected directly to MIX_IN (pin 11) in some applications. follows a classic 3rd-order response. Typical PLL Loop- Bandwidth is set to be approx. 200kHz. The image reject mixer ensures that the receiver’s full sensitivity is achieved without an external filter. For applications where additional selectivity is required, an external filter can be added between the ANT_SW_OUT (pin 7) and MIX_IN (pin 11) pins. The reference frequency for the PLL is provided by an external reference source; normally a TCXO. IF Filter The SE4150L includes a fully integrated Intermediate Frequency (IF) filter which provides excellent interference rejection with no additional external components. The filter has a 3rd order Butterworth bandpass response. The bandpass response has a nominal bandwidth of 2.2 MHz; the nominal center frequency is preset to 4.092 MHz. These parameters ensure very low implementation loss in all frequency plan configurations. AGC and ADC The SE4150L features a linear IF chain with 2-bit SIGN / MAG ADC. SIGN output is pin 20, and MAG output is pin 19. An Automatic Gain Control (AGC) system is included. This provides 50 dB of gain control range so that the output signal level is held at an optimum level at the input of the ADC. The MAG data controls the AGC loop, such that the MAG bit is active (HIGH) for approximately 33% of the time. The SIGN (pin 20) and MAG (pin 19) signals are latched by the falling edge of the sample clock, CLK_OUT (pin 21) within the ADC. The SIGN and MAG signals, once they arrive at the GPS baseband IC, are best re-sampled on the rising edge of CLK_OUT, for optimum sample and hold. The AGC time constant is determined by a single external capacitor, connected between VAGC (pin 1), and VSSN / GND. The settling-time of the AGC is within 10ms with a 10nF capacitor. PLL and Loop Filter The entire Phase-Locked Loop (PLL) generating the local oscillator for the mixer is contained on-chip. TCXO Connection The SE4150L can be used with an external TCXO. The TCXO should have a clipped sinewave signal output which is connected to the TCXO_IN (pin 15) input. The supply to the external TCXO can be connected to pin 13 of the SE4150L. The VCC_TCXO supply is disabled when the SE4150L is in stand-by mode. The VCC_TCXO pin can be left floating if a direct connection from VCC to the power supply of the external TCXO is desired.

Clock and Data Output Coupling The high input sensitivity achieved by the SE4150L’s internal LNA requires careful control of harmonically related sources of interference. For this reason the CLK_OUT (pin 21), SIGN (pin 20) and MAG (pin 19) outputs provide carefully controlled current and slew-rate. The data and clock outputs of the SE4150L are specified to drive up to 15pF load (N.B. the max standard CMOS input capacitance is 10pF). The output drive of the SE4150L can be adjusted with a resistor connected between VDDQ (pin 14) and RVI (pin 12), as shown in the Logic Output Current Drive Adjustment Settings section below. The output current drive is determined by a bias current ratio internal to the SE4150L and the external resistor. A classic three-element RC PLL loop filter has been implemented on-chip between the output of the internal charge pump and GND / VSSN.

The adjustment of the gain and linearity allow the SE4150L to be used in differing environments, either with significant co-located interference sources (e.g. mobile phone) or no interference sources (e.g. PND). LNA Gain & Linearity Selection The SE4150L supports two settings for gain and input IP3 in the on-chip LNA. Supported LNA Gain & Linearity Modes LNA Mode LNA Gain LNA IIP3 Hi Gain 20 dB -6 dBm Lo Gain 17 dB -12 dBm Mixer Gain Selection The SE4150L supports two gain settings for the onchip mixer. Supported Mixer Gain Modes Mixer Mode Mixer Buffer Gain Hi Gain 32 dB Lo Gain 24 dB The following truth table gives the settings for hardware configuration of both the LNA Gain/Linearity and also the Mixer Gain/Linearity. Hardware Configuration LNA Mode Mixer Mode Selection value (HW_<1:0>) Hi Gain Hi Gain 11 Lo Gain Lo Gain 00 Power Management The SE4150L uses RX_EN (pin 5) to put the device into standby. In standby mode, all circuits are off and the device consumes only leakage current. The RX_EN input has a 200 kΩ pull-down resistor to GND, on-chip. This ensures that the RFIC will put itself in standby when the RX_EN controller on the baseband is tri-stated to an impedance much greater than 200 kΩ. The internal LNA can be disabled by connecting the Vcc supply connection to the LNA, VCC_LNA (pin 6) to GND. This may be desirable in some applications, and prevents the LNA from consuming any current, saving approximately 5mA. The sample clock output, CLK_OUT (pin 21) can be kept active by setting CLK_EN (pin 18) pin to logic ‘1’ (HI). This will cause all circuits required to produce the CLK_OUT signal to remain active, even when the receiver is forced into Standby mode (RX_EN (pin 5) set to Logic ‘0’). Logic Interfacing The SE4150L Logic Inputs can either be driven from an external baseband IC, or permanently set by connecting to either VDDN (pin 22) for Logic ‘1’, or GND for Logic ‘0’. The digital interface on the SE4150L, supplied from VDDN, has been designed to operate at the same voltage as the GPS baseband IC. The ANT_DET (pin 8) output is sourced from the antenna current detector, and is also connected to the internal antenna switch; the switch toggles the RF signal source automatically when an external active antenna is connected. The antenna current detector can be overridden by applying a low impedance source (<10kΩ impedance) at VDDN (pin 22) or GND levels to ANT_DET (pin 8), such as a logic output from a GPIO pin on the GPS Baseband IC. This means that automatic switching can be activated by leaving the GPIO pin on the Baseband IC in a high impedance state, or overridden by setting to the appropriate state.

Positive value indicates current source; negative value indicates current sink. ANT_DET (pin 8) Characteristics ANT_DET (pin 8) is an input and output logic signal. In output mode, it operates as an indicator of the current through ANT_BIAS (pin 2). In input mode, an input needs to be applied which overrides the output from the pin, to force the internal antenna-switch.

When ANT_DET (pin 8) used as a logic output. The ANT_DET (pin 8) output drive is asymmetric. When outputting logic ‘0’, the output looks like a current sink of 300uA. When outputting logic ‘1’, the output looks like a pull up resistor of 50kohm to VCC. The 300uA sink is enough to pull the output logic level to GND, with a 10kΩ resistor to VCC. Logic Output Current Drive Adjustment Settings The Logic Outputs on the SE4150L can be adjusted to compensate for parasitics in application board layout. This can be achieved by adding a resistor between RVI (pin 12) and VDDQ (pin 14) as shown below. The additional interface capacitance of PCB tracking and connectors between the SE4150L output and baseband IC input is included in these figures.
