Oscillator input signal. If not being used with an external crystal, this input should be AC 21 OSCin High-Z Input coupled. Complementary oscillator input signal. Can also be used with an external crystal. If not 22 OSCin* High-Z Input being used with an external crystal, this input should be AC coupled. 23 VccOSCin Supply Supply for the OSCin buffer. 24 RFoutEN Input Software programmable output enable pin. Supply 25 VccFRAC Power Supply for the PLL fractional circuitry. (LDO Input) 26 VregFRAC LDO Output Regulated power supply used for the fractional delta-sigma circuitry. 27 GND GND 28 VccDig Supply Supply for digital circuitry, such the MICROWIRE. 29 VccBias Supply Supply for Bias circuitry that is for the whole chip. 30 Bypass Bypass Put a cap to the VccBias pin. 31 VccDiv Supply Supply for the output divider 32 DATA High-Z Input MICROWIRE serial data input. High impedance CMOS input. MICROWIRE clock input. High impedance CMOS input. 33 CLK High-Z Input This pin is used for the digital FSK modulation feature. 34 LE High-Z Input MICROWIRE Latch Enable input. High impedance CMOS input. 35 NC NC No connect. 36 RFout RF Output RF output. Must be AC coupled if used. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) (4) Parameter Symbol Ratings Units Power Supply Voltage Vcc -0.3 to 3.6 V Input Voltage to pins other than Vcc Pins VIN -0.3 to (Vcc+0.3) VIN (5) Storage Temperature TSTG -65 to 150 °C Range Lead Temperature (solder 4 sec.) TL + 260 °C (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only to for the test conditions listed. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) This device is has a ESD rating of ≥ 2500 V Human Body Model (HBM), ≥ 1750 V Charged Device Model (CDM), and ≥400 V Machine Model (MM). It should only be assembled and handled in ESD-free workstations. (4) Stresses in excess of the absolute maximum ratings can cause permanent or latent damage to the device. These are absolute stress ratings only. Functional operation of the device is only implied at these or any other conditions in excess of those given in the (5) Never to exceed 3.6 V.
