It features a high-performance fully field-programmable 200-MHz zero delay buffer designed for high-speed clock distribution. The integrated PLL is designed for low jitter and optimized for noise rejection. These parameters are critical for reference clock distribution in systems using high-performance ASICs and microprocessors. The CY23FP12-002 is fully programmable through volume or prototype programmers, enabling the user to define an application-specific zero delay buffer with customized input and output dividers, feedback topology (internal/external), output inversions, and output drive strengths. For additional flexibility, the user can mix and match multiple functions, listed in Table 2 on page 5, and assign a particular function set to any one of the four possible S1-S2 control bit combinations. This feature enables the implementation of four distinct personalities, selectable with S1-S2 bits, on a single programmed silicon. The CY23FP12-002 also features a proprietary auto power down circuit that shuts down the device in case of a REF failure, resulting in less than 50 μA of current draw. The CY23FP12-002 provides 12 outputs grouped in two banks with separate power supply pins which can be connected independently to either a 2.5 V or a 3.3 V rail. Selectable reference input is a fault tolerance feature which allows for glitch-free switch over to secondary clock source when REFSEL is asserted/deasserted.

This auto power down circuit is disabled internally when one or more of the outputs are configured to be driven directly from the reference clock. PLL Power down Shuts down the PLL when the device is configured as a non-PLL fanout buffer. M[7:0] Assigns an eight-bit value to reference divider –M. The divider can be any integer value See Table 4 from 1 to 256; however, the PLL input frequency cannot be lower than 10 MHz. on page 6 N[7:0] Assigns an eight-bit value to feedback divider –N.

Outputs will be rising edge aligned only to those outputs using this same device setting. 2. When the source of an output pair is set to [111], the output pair becomes lock indicator signal. For example, if the source of an output pair (CLKA0, CLKA1) is set to [111], the CLKA0 and CLKA1, becomes lock indicator signals. In non-invert mode, CLKA0 and CLKA1 signals will be high when the PLL is in lock mode. If CLKA0 is in an invert mode, the CLKA0 will be low and the CLKA1 will be high when the PLL is in lock mode.

When programming, it must be programmed in a device programmer prior to being installed in a circuit. The CY23FP12-002 is based on flash technology, so it can be reprogrammed up to 100 times. This enables fast and easy design changes and product updates, and eliminates any issues with old and out-of-date inventory. The CY23FP12-002 is an extremely flexible clock buffer with up to 12 individual outputs, generated from an integrated PLL. Four variables are used to determine the final output frequency. These are the input reference frequency, the M and N dividers, and the post divider. Samples and small prototype quantities can be programmed on the CY3672-USB programmer. Cypress’s value-added distribution partners and third-party programming systems from BP Microsystems, HiLo Systems, and others are available for large production quantities. CyberClocks™ Software CyberClocks is an easy-to-use software application that allows the user to custom-configure the CY23FP12-002. Users can specify the REF, PLL frequency, output frequencies and/or post-dividers, and different functional options. CyberClocks outputs an industry standard JEDEC file used for programming the CY23FP12-002. CyberClocks can be downloaded free of charge from the Cypress website at www.cypress.com. CY3672-USB Development Kit The Cypress CY3672-USB Developer Kit, in combination with the CY3692 Socket Adapter, is used to program samples and small prototype quantities of the CY23FP12-002. This portable programmer connects to a PC through a USB interface. The JEDEC file output of CyberClocks can be downloaded to the portable programmer for small-volume programming, or for use with a production programming system for larger volumes. Document #: 38-07644 Rev. *B The basic PLL block diagram is shown in Figure 2 on page 4. Each of the six clock output pairs has many post divider options available to it. X is a programmable value between 5 and 130, and 2X is twice that value. There are six post divider options: /1, /2, /3, /4, /X, and /2X. The post divider options can be applied to the calculated PLL frequency or to the REF directly. The feedback is connected either internally to CLKA0 or externally to any output. A programmable divider, M, is inserted between the reference input, REF, and the phase detector. The divider M can be any integer 1 to 256. The PLL input frequency cannot be lower than 10 MHz or higher than 200 MHz. A programmable divider, N, is inserted between the feedback input, FBK, and the phase detector. The divider N can be any integer 1 to 256. The PLL input frequency cannot be lower than 10 MHz or higher than 200 MHz. The output can be calculated as follows: FREF / M = FFBK / N. FPLL = (FREF * N * post divider) / M. FOUT = FPLL / post divider. In addition to above divider options, another option bypasses the PLL and passes the REF directly to the output. FOUT = FREF.
