Functional Block Diagram ASNT2121-KMM is a low power and high-speed digital 1-to-4 deserializer-demultiplexer (DMUX) that functions seamlessly over data rates (fbit) ranging from DC to its maximum frequency. The main function of the part shown in Fig. 1 is to demultiplex an incoming high speed serial differential CML data bit stream dp/dn running at a bit rate of fbit into 4 parallel data channels q0p/q0n, q1p/q1n, q2p/q2n, q3p/q3n running at a bit rate of fbit/4. Differential or single-ended full-rate clock cep/cen must be provided by an external source for the part to function properly. The parallel words and clock divided-by-4 c4op/c4on are transmitted through CML output interfaces. The clock and data outputs are phase-matched to each other resulting in a very little relative skew over the operating temperature range of the device. The part’s I/O’s 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 (see also POWER SUPPLY CONFIGURATION). In the DC-coupling mode, the input signal’s common mode voltage should comply with the specifications shown in ELECTRICAL CHARACTERISTICS. 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. POWER SUPPLY CONFIGURATION The part can operate with either negative supply (vcc = 0.0V = ground and vee = −3.3V), or positive supply (vcc = +3.3V and vee = 0.0V = ground). In case of the positive supply, all I/Os need AC termination when connected to any devices with 50Ohm termination to ground. Different PCB layouts will be needed for each different power supply combination.

ABSOLUTE MAXIMUM RATINGS Caution: Exceeding the absolute maximum ratings shown in Table 1 may cause damage to this product and/or lead to reduced reliability. Functional performance is specified over the recommended operating conditions for power supply and temperature only. AC and DC device characteristics at or beyond the absolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced to ground. Table 1.
