Texas Instruments Inc. (TI) introduced eight new high gain output oscillator buffers that enable designers to save space while also minimizing jitter and power consumption.

Measuring 2-by-2-by-0.55mm, these new oscillator products provide differential signal output in low-voltage differential signaling (LVDS) or low-voltage pseudo emitter-coupled logic (LVPECL) and clock signal amplification for telecommunications switching equipment. The SN65LVDS16/17/18/19 and SN65LVP16/17/18/19 are high-frequency oscillator gain stage buffers supporting LVDS and LVPECL on the high gain outputs in 3.3V or 2.5V systems. The devices afford oscillator designers their choice of rise times2Gbps (LVDS/LVP16 and LVDS/LVP17) or 1Gbps (LVDS/LVP18 and LVDS/LVP 19).

Additionally, the family provides the option of both single-ended input on the LVDS/LVP16 and LVDS/LVP18, and fully differential inputs on the LVDS/LVP17 and LVDS/LVP19. The LVDS/LVP16 and LVDS/LVP18 provide three gain control options from 300mV to 860mV, allowing the designer to optimize the buffer based on system needs.

These new devices offer 3.3V and 2.5V operation, enabling designers to migrate to 2.5V supply as system needs dictate. Each product offers power savings when compared to the nearest competition, with power reductions ranging from 15 percent to 66 percent, added TI.
