21 / 25 page ![]() RF to IF Single Downconverting Mixer 1400MHz to 2500MHz IDT Zero-Distortion TM Mixer 21 Rev1 December 2013 IDTF1751NBGI Datasheet PIN DESCRIPTIONS Pin Name Function 1 VCC Power Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as possible to pin. 2 RF_IN RF Input. Internally matched to 50Ω. Do not apply DC to this pin. 3 GND [RF_RTN] RF input Balun return. Ground this pin 4 GND Internally bonded to GND 5 GND [NC] No Connection. Not internally connected. OK to connect to VCC. OK to connect to GND. 6 VCC [NC] No Connection. Not internally connected. OK to connect to VCC. OK to connect to GND. 7 IF_BIAS Connect the specified resistor from this pin to ground to optimize linearity. 8 VCC Power Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as possible to pin. 9 NC [die ID] This pin serves as the die ID. Leave it unconnected 10 GND Internally bonded to GND 11 LO_IN Local Oscillator Input. This input is internally matched to 50Ω. This pin requires an input DC-blocking capacitor 12 GND Internally bonded to GND 13 GND [LO_ADJ] Ground this pin for best linearity performance. A resistor from this pin to GND can be used to reduce DC power consumption while slightly degrading linearity performance. 14 VCC Power Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close as possible to pin. 15 NC No Connection. Not internally connected. OK to connect to VCC. OK to connect to GND. 16 GND [L_EXT] Provisions for an external inductor. Ground this pin for normal operation. 17 STBY Ground for normal operation. Pull high to disable 18 IF_OUT- Mixer Differential IF Output. Connect pullup inductor from this pin to VCC (see the Typical Application Circuit). 19 IF_OUT+ Mixer Differential IF Output. Connect pullup inductor from this pin to VCC (see the Typical Application Circuit). 20 IF_SET Connect the specified resistor from this pin to ground to set the correct Icc for the IF amplifier. — EP Exposed Pad. Internally connected to GND. Connect to Ground with multiple vias for good thermal relief |
