Product Details

Fig. 1 Functional Block Diagram

ASNT8133-KMC is a high-speed, low-power divider by-1, by-2, or by-4 with increased sensitivity. The part shown in Fig. 1 accepts a CML input clock signal cp/cn with the speed from DC to maximum operational frequency and provides a clean 50% duty cycle output signal cop/con with its frequency defined by the states of div and div4 control signals as shown in Table 1 within the part’s datasheet. The part’s high-speed I/Os support the CML logic interface with on chip 50Ohm termination to vcc and may be used differentially, AC/DC coupled, single-ended, or in any combination. In the DC-coupling mode, the input signal’s common mode voltage should comply with the specifications shown in ELECTRICAL CHARACTERISTICS within the part’s datasheet. In the AC-coupling mode, the input termination provides the required common mode voltage automatically. The differential DC signaling mode is recommended for optimal performance.
