MAX9223/MAX9224 are 22-bit serializer/deserializer chipsets from Maxim that use low-current differential signaling (LCDS) for low EMI, high common-mode noise immunity, and ground-shift tolerance. They are ideal for cell phones, LCDs, and digital cameras.
The MAX9223 and MAX9224 are 22‑bit serializer/deserializer chipsets that reduce wiring by converting parallel LCD data to a single differential pair. They operate at 5 MHz to 10 MHz clock rates, delivering 110 Mbps to 220 Mbps serial data rates for cell‑phone QVGA and QCIF displays. Features include low‑power operation, automatic word‑boundary detection, and power‑down control via the serial link.
The devices are supplied in a 28‑pin TQFN package (4 mm × 4 mm × 0.8 mm) with an exposed paddle. Electrical specifications cover supply voltage ranges of +2.375 V to +3.465 V (core) and +1.71 V to +3.465 V for the output buffer, power‑down currents as low as 0.5 µA, and an operating temperature range of –40 °C to +85 °C. Detailed pin descriptions, timing diagrams, and package information are included.
