TCXO with -55 to +95°C Operating Temperature in a 5 x 7mm footprint ! New AST3TQ Series ABRACON’s AST3TQ series offers wide operating temperature, precision fixed clock TCXO’s in a small profile 5 x 7 x 1.9 mm SMT package. These devices are available from 10MHz to 40MHz carrier frequencies with LVCMOS output; offering ±500 ppb frequency stability over -55ºC to +95ºC operating temperature. AST3TQ series complies with Stratum-III requirement of < ±4.60ppm all-Inclusive error over 20-year product life. Temperature stability options include ±100ppb over -40ºC to +85ºC, ±280ppb over -50ºC to +90ºC and ±500ppb over -55ºC to +95ºC operating temperature range. With maximum current drain of 7mA @ 40MHz, these devices offer OCXO level accuracy over a wide operating temperature range, with minimal power consumption.
