The MAX3264/MAX3265/MAX3268/MAX3768/MAX3765 is a optical receiver from Texas Instruments. It supports transmission speed of 1.25Gbps and 2.5Gbps, and has low jitter and programmable loss-of-signal indication.
The MAX3264, MAX3265, MAX3268, MAX3269, MAX3765 and MAX3768 are limiting amplifiers designed for Gigabit Ethernet, Fibre Channel, ATM and other high‑speed optical receiver applications. They operate from a supply voltage of +3.0 V to +5.5 V and support data rates of 1.25 Gbps (MAX3264/3268/3768) or 2.5 Gbps (MAX3265/3269/3765). Features include low deterministic jitter, programmable loss‑of‑signal detection, optional squelch, and CML or PECL output options.
The devices are offered in 10‑pin uMAX and 16‑pin TSSOP packages, with detailed absolute‑maximum ratings, electrical characteristics, typical operating curves, pin descriptions and package dimensions provided for designers.
