Page 5 of 10 PE9704 Product Specification Functional Description Prescaler Bypass Mode The PE9704 consists of a prescaler, counters, a phase detector, and control logic. The dual modulus prescaler divides the VCO frequency by either 10 or 11, depending on the value of the modulus select. Counters “R” and “M” divide the reference and prescaler output, respectively, by integer values stored in a 20-bit register. An additional counter (“A”) is used in the modulus select logic. The phase-frequency detector generates up and down frequency control signals. The control logic includes a selectable chip interface. Data can be written via a serial bus or hardwired directly to the pins. There are also various operational and test modes and a lock detect output. Setting the enhancement register bit PB “high” allows FIN to bypass the ÷10/11 prescaler. In this mode, the prescaler and A counter are powered down, and the input VCO frequency is divided by the M counter directly. This mode is only available when using the serial port to set the frequency control bits. The following equation relates FIN to the reference frequency FR: (3) Reference Counter The reference counter chain divides the reference frequency FR down to the phase detector comparison frequency fc. Main Counter Chain Normal Operating Mode Setting the PB control bit “low” enables the ÷10/11 prescaler. The main counter chain then divides the RF input frequency (FIN) by an integer derived from the values in the “M” and “A” counters. In this mode, the output from the main counter chain (fp) is related to the VCO frequency (FIN) by the following equation: fp = FIN / [10 x (M + 1) + A] where A ≤ M + 1, 1 ≤ M ≤ 511 FIN = (M + 1) x (FR / (R+1)) ) where 1 ≤ M ≤ 511 (1) The output frequency of the 6-bit R Counter is related to the reference frequency by the following equation: fc = FR / (R + 1) where 0 ≤ R ≤ 63 (4) Note that programming R with “0” will pass the reference frequency (FR) directly to the phase detector. When the loop is locked, FIN is related to the reference frequency (FR) by the following equation: FIN = [10 x (M + 1) + A] x (FR / (R+1)) where A ≤ M + 1, 1 ≤ M ≤ 511 (2) A consequence of the upper limit on A is that FIN must be greater than or equal to 90 x (FR / (R+1)) to obtain contiguous channels. The A counter can accept values as high as 15, but in typical operation it will cycle from 0 to 9 between increments in M. Programming the M counter with the minimum allowed value of “1” will result in a minimum M counter divide ratio of “2”. ©2003-2006 Peregrine Semiconductor Corp. All rights reserved.

After the falling edge of E_WR, the data provides control bits as shown in Table 8. These bits are active when the Enh input is “low”. Serial Interface Mode Serial Interface Mode is selected by setting the DMODE input “low”. Direct Interface Mode While the E_WR input is “low”, serial data (DATA input), B0 to B19, is clocked into a buffer register on the rising edge of CLOCK, LSB (B0) first. The contents from this buffer register are transferred into the frequency control register on the rising edge of S_WR according to the timing diagram shown in Figure 4. This data controls the counters as shown in Table 7. Direct Interface Mode is selected by setting the DMODE input “high”. In this mode, the counter values are set directly at external pins as shown in Table 7 and Figure 2. All frequency control register bits are addressable except PB (it is not possible to bypass the ÷10/11 dual modulus prescaler in Direct Mode). While the E_WR input is “high”, serial data (DATA input), B0 to B7, is clocked into a buffer register on the rising edge of CLOCK, LSB (B0) first. The contents from this buffer register are transferred into the enhancement register on the falling edge of E_WR according to the timing diagram shown Table 7.

It has two outputs, PD_U, and PD_D. If the divided VCO leads the divided reference in phase or frequency (fp leads fc), PD_D pulses “low”. If the divided reference leads the divided VCO in phase or frequency (fc leads fp), PD_U pulses “low”. The width of either pulse is directly proportional to phase offset between the two input signals, fp and fc. The phase detector gain is 430 mV / radian. PD_U and PD_D are designed to drive an active loop filter which controls the VCO tune voltage. ©2003-2006 Peregrine Semiconductor Corp. All rights reserved. Page 8 of 10 PD_U pulses result in an increase in VCO frequency and PD_D results in a decrease in VCO frequency. Software tools for designing the active loop filter can be found at Peregrine’s web site: www.psemi.com Lock Detect Output A lock detect signal is provided at pin LD, via the pin CEXT (see Figure 1). CEXT is the logical “NAND” of PD_U and PD_D waveforms, driven through a series 2 kΩ resistor. Connecting CEXT to an external shunt capacitor provides integration of this signal.
