Functional Block Diagram The temperature-stable linear amplifier ASNT6142-KHC, which is fabricated in an advanced SiGe technology, provides low-jitter broadband variable signal amplification between its input inp/inn and output outp/outn signal ports and is intended for use in high-speed communication systems. Gain adjustment is performed through the external control port vgc. A graph of the amplifier’s single-ended gain vs. vgc (where vcc=0V and x-axis values are settings below vcc) is shown below. Differential gain is found by adding 6dB to these y-axis numbers. Fig. 2. Single-ended Gain vs. Vgc Rev. 1.1.2 2 May 2020 Advanced Science And Novel Technology Company, Inc. 2790 Skypark Drive Suite 112, Torrance, CA 90505 Offices: 310-530-9400 / Fax: 310-530-9402 www.adsantec.com The part’s 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 (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. The on-chip peak detector delivers a single-ended output voltage pkdet proportional to the input signal’s amplitude. Additional control ports dcinp and dcinn can be used for input signal common-mode voltage adjustment. POWER SUPPLY CONFIGURATION The part can operate with either a negative supply (vcc = 0.0V=ground and vee = -3.3V), or a 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. All the characteristics detailed below assume vcc = 0.0V and vee = -3.3V. 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. Table 1.
