2 / 16 page Connection Diagrams Pin Descriptions Pin No. Pin Name I/O Description 24-Pin CSP 20-Pin TSSOP 24 1 V CC1 — Power supply voltage input for RF analog and RF digital circuits. Input may range from 2.7V to 5.5V. V CC1 must equal VCC2. Bypass capacitors should be placed as close as possible to this pin and be connected directly to the ground plane. 2 2 Vp1 — Power supply for Main charge pump. Must be ≥ V CC. 33 CP o1 O Internal Main charge pump output. For connection to a loop filter for driving the input of an external VCO. 4 4 GND — Ground for Main digital circuitry. 55 f IN1 I Main prescaler input. Small signal input from the VCO. 66 f IN1b I Main prescaler complementary input. For single ended operation, a bypass capacitor should be placed as close as possible to this pin and be connected directly to the ground plane. 7 7 GND — Ground for Main analog circuitry. 8 8 OSC in I Oscillator input. The input has a V CC/2 input threshold and can be driven from an external CMOS or TTL logic gate. 10 9 GND — Ground for Aux digital, MICROWIRE, FoLD, and oscillator circuits. 11 10 Fo/LD O Multiplexed output of the Main/Aux programmable or reference dividers, Main/Auxiliary lock detect signals and Fastlock mode. CMOS output (see Programmable Modes in the Datasheet). 12 11 Clock I High impedance CMOS Clock input. Data for the various counters is clocked in on the rising edge, into the 22-bit shift register. 14 12 Data I Binary serial data input. Data entered MSB first. The last two bits are the control bits. High impedance CMOS input. 15 13 LE I Load enable. High impedance CMOS input. When LE goes HIGH, data stored in the shift registers is loaded into one of the 4 appropriate latches (control bit dependent).
