Functional Description
The CY7B9930V and CY7B9940V High-Speed Multifrequency PLL Clock Buffers offer user-selectable control over system clock functions. This multiple output clock driver provides the system integrator with functions necessary to optimize the timing of high performance computer or communication systems. Ten configurable outputs can each drive terminated transmission lines with impedances as low as 50 while delivering minimal and specified output skews at LVTTL levels. The outputs are arranged in three banks. The FB feedback bank consists of two outputs, which allows divide-by functionality from 1 to 12. Any one of these ten outputs can be connected to the feedback input as well as driving other inputs. Selectable reference input is a fault tolerance feature that allows smooth change over to secondary clock source, when the primary clock source is not in operation. The reference inputs are configurable to accommodate both LVTTL or differential (LVPECL) inputs. The completely integrated PLL reduces jitter and simplifies board layout.

Divide Matrix
The Divide Matrix is comprised of three independent banks: two banks of clock outputs and one bank for feedback. Each clock output bank has two pairs of low-skew, high fanout output buffers ([1:2]Q[A:B][0:1]), and an output disable (DIS[1:2]). The feedback bank has one pair of low-skew, high fanout output buffers (QFA[0:1]). One of these outputs may connect to the selected feedback input (FBKA+). This feedback bank also has two divider function selects FBDS[0:1]. The divide capabilities for each bank are shown in Table 2. Table 2. Output Divider Function Function Selects

Block Diagram Description
Phase Frequency Detector and Filter
These two blocks accept signals from the REF inputs (REFA+, REFA-, REFB+ or REFB-) and the FB input (FBKA). Correction information is then generated to control the frequency of the Voltage Controlled Oscillator (VCO). These two blocks, along with the VCO, form a Phase-Locked Loop (PLL) that tracks the incoming REF signal. The RoboClockIITM Junior has a flexible REF input scheme. These inputs allow the use of either differential LVPECL or single ended LVTTL inputs. To configure as single ended LVTTL inputs, leave the complementary pin to 1.5V), then use the other input pin as an LVTTL input. The REF inputs are also tolerant to hot insertion. The REF inputs can be changed dynamically. When changing from one reference input to the other reference input of the same frequency, the PLL is optimized to ensure that the clock outputs period is not less than the calculated system budget (tMIN = tREF (nominal reference clock period) - tCCJ (cycle-to-cycle jitter) - tPDEV (max. period deviation)) while reacquiring lock.

VCO, Control Logic, and Divide Generator
The VCO accepts analog control inputs from the PLL filter block. The FS control pin setting determines the nominal operational frequency range of the divide by one output (fNOM) of the device. fNOM is directly related to the VCO frequency. There are two versions of the RoboClockII Junior, a low speed device (CY7B9930V) where fNOM ranges from 12 MHz to 100 MHz, and a high speed device (CY7B9940V), which ranges from 24 MHz to 200 MHz. The FS setting for each device is shown in Table 1. The fNOM frequency is seen on "divide-by-one" outputs. Table 1. Frequency Range Select CY7B9930V FS[1] LOW MID HIGH fNOM (MHz) Min. 12 24 48 Max. 26 52 100 CY7B9940V fNOM (MHz) Min. 24 48 96 Max. 52 100 200[2]
Output Disable Description
The outputs of Bank 1 and Bank 2 can be independently put into a HOLD OFF or high impedance state. The combination of the Output_Mode and DIS[1:2] inputs determines the clock outputs' state for each bank. When the DIS[1:2] is LOW, the outputs of the corresponding bank are enabled. When the DIS[1:2] is HIGH, the outputs for that bank are disabled to a high impedance (HI-Z) or HOLD OFF state depending on the Output_Mode input. Table 3 defines the disabled output functions.
Notes 1. The level to be set on FS is determined by the "nominal" operating frequency (fNOM) of the VCO. fNOM always appears on an output when the output is operating in the undivided mode. The REF and FB are at fNOM when the output connected to FB is undivided. 2. The maximum output frequency is 200 MHz.

The HOLD OFF state is designed as a power saving feature. An output bank is disabled to the HOLD OFF state in a maximum of six output clock cycles from the time when the disable input (DIS[1:2]) is HIGH. When disabled to the HOLD OFF state, outputs are driven to a logic LOW state on its falling edge. This ensures the output clocks are stopped without glitch. When a bank of outputs is disabled to HI-Z state, the respective bank of outputs go HI-Z immediately. Table 3. DIS[1:2] Pin Functionality OUTPUT_MODE HIGH/LOW HIGH LOW MID DIS[1:2]/FBDIS LOW HIGH HIGH X Output Mode ENABLED HI-Z HOLD-OFF FACTORY TEST If the feedback clock is removed after LOCK has gone HIGH, a Watchdog circuit is implemented to indicate the out-of-lock condition after a timeout period by deasserting LOCK LOW. This timeout period is based upon a divided down reference clock. This assumes that there is activity on the selected REF input. If there is no activity on the selected REF input then the LOCK detect pin may not accurately reflect the state of the internal PLL.
Factory Test Mode Description
The device enters factory test mode when the OUTPUT_MODE is driven to MID. In factory test mode, the device operates with its internal PLL disconnected; the input level supplied to the reference input is used in place of the PLL output. In TEST mode the selected FB input must be tied LOW. All functions of the device remain operational in factory test mode except the internal PLL and output bank disables. The OUTPUT_MODE input is designed as a static input. Dynamically toggling this input from LOW to HIGH may temporarily cause the device to go into factory test mode (when passing through the MID state). Factory Test Reset When in factory test mode (OUTPUT_MODE = MID), the device is reset to a deterministic state by driving the DIS2 input HIGH. When the DIS2 input is driven HIGH in factory test mode, all clock outputs go to HI-Z; after the selected reference clock pin has five positive transitions, all the internal finite state machines (FSM) are set to a deterministic state. The deterministic state of the state machines depends on the configurations of the divide selects and frequency select input. All clock outputs stay in high impedance mode and all FSMs stay in the deterministic state until DIS2 is deasserted. When DIS2 is deasserted (with OUTPUT_MODE still at MID), the device reenters factory test mode.
Lock Detect Output Description
The LOCK detect output indicates the lock condition of the integrated PLL. Lock detection is accomplished by comparing the phase difference between the reference and feedback inputs. Phase error is declared when the phase difference between the two inputs is greater than the specified device propagation delay limit (tPD). When in the locked state, after four or more consecutive feedback clock cycles with phase errors, the LOCK output is forced LOW to indicate out-of-lock state. When in the out-of-lock state, 32 consecutive phase errorless feedback clock cycles are required to allow the LOCK output to indicate lock condition (LOCK = HIGH).

Description Reference Inputs: These inputs operate as either differential PECL or single ended TTL reference inputs to the PLL. When operating as a single ended LVTTL input, leave the complementary input must be left open. Reference Select Input: The REFSEL input controls reference input configuration. When LOW, it uses the REFA pair as the reference input. When HIGH, it uses the REFB pair as the reference input. This input has an internal pull down. Frequency Select: Set this input according to the nominal frequency (fNOM). See Table 1. Feedback Divider Function Select. These inputs determine the function of the QFA0 and QFA1 outputs. See Table 2. Output Disable: Each input controls the state of the respective output bank. When HIGH, the output bank is disabled to the "HOLD OFF" or "HI-Z" state; the disable state is determined by OUTPUT_MODE. When LOW, the [1:4]Q[A:B][0:1] is enabled. See Table 3. These inputs each have an internal pull down. PLL Lock Indicator: When HIGH, this output indicates that the internal PLL is locked to the reference signal. When LOW, the PLL is attempting to acquire lock. Output Mode: This pin determines the clock outputs' disable state. When this input is HIGH, the clock outputs disable to high impedance (HI-Z). When this input is LOW, the clock outputs disables to "HOLD OFF" mode. When in MID, the device enters factory test mode. Clock Feedback Output: This pair of clock outputs connects to the FB input. These outputs have numerous divide options. The function is determined by the setting of the FBDS[0:1] pins. Clock Output. Output Buffer Power: Power supply for each output pair. Internal Power: Power supply for the internal circuitry. Device Ground.

Note 4. These inputs are normally wired to VCC, GND, or left unconnected (actual threshold voltages vary as a percentage of VCC). Internal termination resistors hold the unconnected inputs at VCC/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional tLOCK time before all data sheet limits are achieved.
